and make it a bit more themeable.

Plus minor formatting changes in order to fit lines into 80 characters.

* Streamline message template retrieval, and make it pluggable too.
* Update the copyright notices, and remove the amateur GPL header
  (drupal.org now explicitely states GPLv2+ anyways).

nearer to the actual output (although in practice it shouldn't make
a lot of difference).

  separate function. Also, reduce complexity by moving replacements out of
  the _temporary_invitation_get_message_template() function.
* Provide a token for the invitation creation date.
* Sort loaded arrays by creation date (newest first).

that might be set by hook_user() and confuse guest users as they don't
get to the target path.

'temporary-invitation-login' still doesn't work in that case.

* Change form callback signature & Co. so that the $destination parameter
  is not required anymore, takes the current page as default.
* Introduce an option "Don't assign roles to existing users".
* And update the .install file so that everything works like before.

Uses drupal_get_destination() instead of a fixed base path,
makes it possible to have the "temporary-invitation" path cached again,
and removes one more non-cached path while making it possible for
external themers to use the temporary_invitation_overview() function
and have it redirect correctly.
Whoo.

choice but to make this a non-cached path even if the path is stable.

expiration date can be displayed in the preview already.

* Make $mail an object instead of an array, more consistent this way.
* The return value of loginticket_login() is a user object, not a boolean.

while reviewing them.

* Fix the workflow-ng user argument handlers, as global $user is not
  always the host user. Instead, introduce two API functions that
  take care of determining the user.
* Rename the token type 'new_temporary_invitation' to
  'temporary_invitation_with_passcode', which fits better
  as it also applies to logins.

spaces are not needed, and fix a few minor issues.

update.php because mail templates are converted to the Token format.

when it has been filled with (unique) values. Grave update procedure bug.

It now works not only better and more usable, but also rather different.
Therefore, HEAD is being revived as 5.x-2.x development branch until 6.x-1.x opens.

The major change is that I was able to get rid of quite a few settings
in favor of letting users draft their invitation mails by themselves.
It is now compulsory to have mails sent to the invited entity, which
includes the nice feature of integrating login codes inside the mail
automatically. Additionally, there's a preview where the user can
have a look at the complete mail (amended with login information)
before sending it to the invitee.

That, and a freaking lot of other cool features:
* Multiple users can now send invitations to the same mail address.
  (Yeah, that was a pretty grave design bug in 5.x-1.x. Fixing it
   required to change the database schema a bit, so run update.php.)
* Users that already exist (from a mail address point of view)
  can now also be invited, and don't even get blocked/deleted
  when the invitation expires. Whoo!
* The admin form is so much more straightforward now.
  I also claim the same for the invitation management form.
* Support for direct login URLs in addition to the login form.
* The module now adapts also dynamic menu paths to aliases
  of the static (cached) paths. That is, http://example.org/my-login/123abc
* An additional 'login' op for hook_temporary_invitation().
* I surely forgot something. But well, you get the point :)

Make dead sure you run update.php, otherwise you're screwed.
Quite a lot of the configuration options will be deleted in the process,
but you'll soon recognize that you only needed those to work around
conceptual defiencies in 5.x-1.x.
Also, updating Login Ticket API is pretty much a good idea if
you want the "multiple invitations for the same person" feature,
or the 'login' op in the hook.

Really, I guess that was my largest commit message ever.
And rightly so. Hah. Like,
"Temporary Invitation 2.0: so much better than the first one."

Initial commit of the Temporary Invitation module. Enables site users to invite guests for a limited timespan, and deletes or blocks guest user accounts after the invitation has expired.
