jordi fita mas f1bf1f896d Implement login cookie, its verification, and logout
At first i thought that i would need to implement sessions, the ones
that keep small files onto the disk, to know which user is talking to
the server, but then i realized that, for now at least, i only need a
very large number, plus the email address, to be used as a lookup, and
that can be stored in the user table, in a separate schema.

Had to change login to avoid raising exceptions when login failed
because i now keep a record of login attemps, and functions are always
run in a single transaction, thus the exception would prevent me to
insert into login_attempt.  Even if i use a separate procedure, i could
not keep the records.

I did not want to add a parameter to the logout function because i was
afraid that it could be called from separate users.  I do not know
whether it is possible with the current approach, since the settings
variable is also set by the same applications; time will tell.
