Convert the login variables to a struct with parsing and validation It is a lot of code having to check the login variables inside the POST handler, and i could not mark each input field individually as invalid because the generic errors array i was using did no identify which field had the error. Thus, i use more or less the same technique as with Numerus: a struct with the value and the error message. This time the input field does not have the label and extra attributes because i believe this belongs to the template: if i want do reuse the same form template, i should create a common template rather than defining everything in Go. The name is a bit different, however, because it has meaning both to the front and back ends, as it needs to be exactly the same. Writing it twice is error-prone, as with a rename i could easily forget to change one or the other, and here i see value in having that in Go, because it is also used in code.

Add profile form, inside a user menu This is the first form that uses HTMx, and can not return a 400 error code because otherwise HTMx does not render the content. Since now there are pages that do not render the whole html, with header and body, i need a different layout for these, and moved the common code to handle forms and such a new template file that both layouts can use. I also need the request in template.MustRender to check which layout i should use. Closes #7.
