fasttoggle 6.x-1.6

A large number of changes, including backporting of all the features that have been added in the Drupal 7 version:

- Admin interface for sitewide control of fasttoggleable roles.
- Per node type control of fasttoggling.
- Options to disable enhancement of the node and user overview pages.
- Optional support for blocking user 1.
- Watchdog logging
- Support for toggling user roles

I intend to do a big rework next which will make integration with other modules a much simpler task.
