auth_pgsql update for auth_cryptPassword

added support for the new auth_cryptPassword() and the corresponding
verify functions

   - $conf['auth']['pgsql']['userinfo'] is now used to verify passwords;
     therefore it also needs to return the crypted passwords which in
     turn makes $conf['auth']['pgsql']['passcheck'] obsolete
   - changed the pass collumn in the users table from varchar(32)
     to varchar(255); just to be on the safe side.

added support for an optional pgsql "port" option
($conf['auth']['pgsql']['port'])

added basic support for adding new users
this needs the $conf['auth']['pgsql']['createuser'] option including
a corresponding sql function
