- Patch #721086 by rfay, aspilicious, andypost: create tests for system actions, clean up token replacement, clean up triggers.

- Patch #348448 by mfb, c960657, marvil07, cdale, jpmckinney: fixed PHP strict warnings when running tests and for PHP 5.3.

- Patch #241013 by Pedro Lozano, drewish, andypost, mr.baileys: actions only trigger one action per node page load.

- Patch #705306 by moshe weitzman: user_cancel_delete() method calls into a 'standard' user_delete_multiple() API.

#306540 by halstead, Dave Reid, jvandyk, eMPee584: Fixed Orphaned assigned actions still triggered and cannot be removed.

- Patch #502190 by jhodgdon, stella, sun: hook implementation headers out of compliance with standards.

Roll-back of #595084; type-hinting parameters at stdClass makes it so you can't ever pass in another type of class.

#600974 by effulgentsia, JohnAlbin, sun, and Damien Tournoud: Allow theme functions to take one argument without any hacks. NOTE: This is an API change in hook_theme().

#118345 by sun: Make user.module conform to standard presave/insert/update/form_alter hook paradigm.

- Patch #572618 by effulgentsia, pwolanin, sun: all theme functions should take a single argument. Code clean-up and performance improvement. Woot.

- Patch ##525540 by jvandyk, sun, jhodgdon, fago | webchick, TheRec, Dave Reid, brianV, sun.core, cweagans, Dries: gave trigger.module and includes/actions.inc an API overhaul.  Simplified definitions of actions and triggers and removed dependency on the combination of hooks and operations. Triggers now directly map to module hooks.

#497118 by chx, catch, pwolanin, JoshuaRogers, and Jacob Singh: Remove the function registry. While the hope was that this would result in improved performance for low-end hosts, it comes at the expense of critical development experience problems and less benefit than something like APC. Class registry remains intact to facilitate autoloading.

Of all the patches to accidentally commit without a message. :( Rolling back registry rip. Let's try that again.

#296322 by cwgordon7 andSenpai: Fix horribly broken trigger module and add tests so we don't do it anymore.

#246096 by andypost, mr.baileys, and Sutharsan: Fix typo so that cron triggers may be executed (with tests).
