jordi fita mas 216ae20638 Add the campsite relation, HTTP handlers, and form
For now, there is only the label, type, and active fields.  We will need
some field to hold the area on the map, but this requires #4, and
possibly #6, to be finished.

Part of #27.

jordi fita mas 8b5a45299e Return HTTP 404 response for non-active campsite’s public pages
At first i thought i had to return HTTP 410 gone in this case, but
HTTP Semantics RFC[0] says that “The 410 (Gone) status code indicates
that […] this condition is likely to be permanent. If the origin server
does not know […] whether or not the condition is permanent, the status
code 404 (Not Found) ought to be used instead.”

A non-active campsite type does not mean “deleted”, but rather
temporarily disabled, thus a 404 is the appropriate code.

jordi fita mas 208952b964 Add the Active field to the campsite type’s edit form and function
In the new form this field is hidden and always active, because it makes
no sense to add an inactive campsite type.

jordi fita mas d117ce5027 Add public page for campsite type, and function to edit them
Had to export and move PublicPage struct to template because i can not
import app from campsites/types: app already imports campsite for the
http handler, and it, in turn, imports the types package for its own
http handler; an import loop.

Also had to replace PublicPage.MustRender with a Setup function because
the page passed down to html/template was the PublicPage struct, not
whatever struct embeds it.  I was thinking more of Java inheritance here
rather than struct embedding.

jordi fita mas e128680e9a Split templates and handlers into admin and public
I need to check that the user is an employee (or admin) in
administration handlers, but i do not want to do it for each handler,
because i am bound to forget it.  Thus, i added the /admin sub-path for
these resources.

The public-facing web is the rest of the resources outside /admin, but
for now there is only home, to test whether it works as expected or not.

The public-facing web can not relay on the user’s language settings, as
the guest user has no way to set that.  I would be happy to just use the
Accept-Language header for that, but apparently Google does not use that
header[0], and they give four alternatives: a country-specific domain,
a subdomain with a generic top-level domain (gTLD), subdirectories with
a gTLD, or URL parameters (e.g., site.com?loc=de).

Of the four, Google does not recommend URL parameters, and the customer
is already using subdirectories with the current site, therefor that’s
what i have chosen.

Google also tells me that it is a very good idea to have links between
localized version of the same resources, either with <link> elements,
Link HTTP response headers, or a sitemap file[1]; they are all
equivalent in the eyes of Google.

I have choosen the Link response headers way, because for that i can
simply “augment” ResponseHeader to automatically add these headers when
the response status is 2xx, otherwise i would need to pass down the
original URL path until it reaches the template.

Even though Camper is supposed to be a “generic”, multi-company
application, i think i will stick to the easiest route and write the
templates for just the “first” customer.

jordi fita mas 1b923a9f65 Add add_campsite_type function and call it from Go with a proper form
This form has an “HTML field”, which is just a <textarea> but “improved”
with the use of Automattic’s isolated block editor[0], a repackaged
Gutenberg’s editor playground as full-featured multi-instance editor
that does not require WordPress.

I do not want to use Node to build this huge, over-engineered piece of …
software. Therefore, i downloaded the released “browser” package, and
added the required React bundle, like i do with HTMx.  This will hold
until i need a new custom block type; let’s hope i will not need it.

jordi fita mas f65110824e Add the company’s slug in the URL before company-dependent handlers
I really doubt that they are going to use more than a single company,
but the application is based on Numerus, that **does** have multiple
company, and followed the same architecture and philosophy: use the URL
to choose the company to manage, even if the user has a single company.

The reason i use the slug instead of the ID is because i do not want to
make the ID public in case the application is really used by employees
of many unrelated companies: they need not need to guess how many
companies there are based on the ID.

I validate this slug to be a valid UUID instead of relaying on the
query’s empty result because casting a string with a malformed value to
UUID results in an error other than data not found.  Not with that
select, but it would fail with a function parameter, and i want to add
that UUID check to all functions that do use slugs.

I based uuid.Valid function on Parse() from Google’s uuid package[0]
instead of using regular expression, as it was my first idea, because
that function is an order of magnitude faster in benchmarks:

  goos: linux
  goarch: amd64
  pkg: dev.tandem.ws/tandem/numerus/pkg
  cpu: Intel(R) Core(TM) i5-6200U CPU @ 2.30GHz
  BenchmarkValidUuid-4            36946050                29.37 ns/op
  BenchmarkValidUuid_Re-4          3633169               306.70 ns/op

The regular expression used for the benchmark was:

  var re = regexp.MustCompile("^[a-fA-F0-9]{8}-[a-fA-F0-9]{4}-4[a-fA-F0-9]{3}-[8|9|aA|bB][a-fA-F0-9]{3}-[a-fA-F0-9]{12}$")

And the input parameter for both functions was the following valid UUID,
because most of the time the passed UUID will be valid:

  "f47ac10b-58cc-0372-8567-0e02b2c3d479"

I did not use the uuid package as is, even though it is in Debian’s
repository, because i only need to check whether the value is valid,
not convert it to a byte array.  As far as i know, that package can not
do that.

Adding the Company struct into auth was not my intention, as it makes
little sense name-wise, but i need to have the Company when rendering
templates and the company package has templates to render, thus using
the company package for the Company struct would create a dependency
loop between template and company.  I’ve chosen the auth package only
because User is also there; User and Company are very much related in
this application, but not enough to include the company inside the user,
or vice versa, as the User comes from the cookie while the company from
the URL.

Finally, had to move methodNotAllowed to the http package, as an
exported function, because it is used now from other packages, namely
campsite.

jordi fita mas cfa330bce4 Add the mock-up form for new campsite type
It does nothing, but i need it to discuss with Oriol.

Now there are more than a single package that requires shiftPath, so
i moved it to http and an exported function, ShiftPath.
