User module and DA modules:

  + Updated the documentation to use a Jabber or Drupal IDs instead of
    Deplhi IDs (as delphi.module won't be part of the default distro).
    Drupal and Jabber authentication make a better example.

  + added missing localization / t() functions in
    user_validate_authmaps()

  + applied coding convention:
      * fixed indentation
      * removed "EOF"; and <<EOFs from user module
      * changed some HTML into XHTML: use small letters, quote
        attributes
      * quoted some array indices: $edit[foo] --> $edit["foo"]

  + removed some useless sprintf()'s

  + removed hard-coded references to drop.org.

  + I don't think the authentication methods should /know/ there help
    link.  Instead, the user module should now where to find the help
    (it does by knowing the hook to look for), and it is the user
    module that should take care of exporting the help to the preferred
    location:
      * removed the "link" field from the $info field in drupal_info
        and jabber_info; it wasn't used anyway?

  + removed the "maintainer" and "maintaineremail" from the auth
    modules; we don't keep this info in the other modules either so
    I don't see a reason to do so here.
