rules 6.x-1.1

This release features a lot of great improvements implemented by klausi during his Google Summer of Code project. Shortly, the since 1.0 the following features have been added:

* Improved the rules scheduler. Now tasks can be easily re-scheduled and deleted by an action. Also there is now some admin interface that lists scheduled tasks and allows manual deletion of scheduled tasks. (by klausi!)
* Added a new rules-forms sub-module which comes with events, conditions and actions for rule-based manipulation of all forms! (by klausi) Awesome!
* The rules UI got new icons and some small usability improvements! Again, thanks klausi!

Also there is an experimental integration with the features module currently depending on the patch from http://drupal.org/node/551490. This is still work in progress, but brave users can already test it and create features built of rules!

After updating, run update.php!
(There will be only an update if you have the rules scheduler module activated, but just run update.php in any case).

Note:
If you are using the rules scheduler module watch out for timezone issues! Klausi fixed potential timezone troubles with the "Scheduling rule set" action, thus *all* date values specified there are now interpreted as GMT. Best check your configurations to specify the date in the right timezone, if that matters to you.
