- Refactored the throttle module. Patch by Jeremy and me.
* There are only two throttle levels instead of 5, namely 'enabled' and 'disabled'. This makes it a _lot_ easier to predict when the throttle will kick in. However, if you maintain a module that is throttle-aware, it needs to be updated! * The throttle mechanism now uses the current number of anonymous users or the current number of authenticated users to kick in. This is a _lot_ more intuitive than the old throttle mechanism. * The throttle block has been removed -- you can now use the "Who's online" block to determine the good throttle settings. * Most of the documentation has been removed because it was deprecated. * It's less code!
