ItEr39S10CUAltaUsuario: implemented the password field in user edition page

If the password field is left empty when *editing* a user, its password
remains unchanged.
If it's left empty when *creating* a user, the business layer will complain.
TODO: make this behaviour explicit for the user (label with instructions,
ConstraintChecker when creating a user...)
