Checkpoint checkin. Partial implementation of page task with generic subtasks, plus revamp of arguments, new access plugins (stolen from Views), updates to the wizard to make it fully compatible with the modal and some minor improvements to make it more flexible.

Add a little AJAX support to the wizard tool. I think it still needs more but I will not be sure what until I actually need to use it.

A tool to facilitate multi-step wizards. I do not think this is quite finished yet but it handles the simple case pretty well.

- a tool for AJAX, which is the next generation tool based on what Views uses.
- a tool for modals -- completely ripping the modal out of Panels.
- moving plugins for 'arguments', 'relationships' and 'contexts' into CTools.

Add callbacks to the collapsible so that it can be trivially transformed into other things like an accordion. Add accordion functionality to the task admin UI.

Add a separate "weights" table for delegator items. Please note that this commit will require you to reinstall the module to get the new table.

More items knocked off the TODO list; brought the css filter by dmitrig01 and sdboyer from Panels Page into ctools.

Checkpoint check in. The node_view task now functions, though there are still a few areas to clean up. The task handlers have been moved to Panels.

Chaos Tools API initial, early checkin. This module provides 4 API tools, plus an early version of the delegator module. See http://views2.logrus.com/overrides for a discussion of delegator.module.
