forward with the 7.x port!

Committing in a collection of ongoing port work from #589636, so that we can stop trying to track it all in patches.

Will make merging in changes (with an outside dvcs) from the 6--1 branch easier, anyway.

#564492: by Roger Lopez: Change default class includes from .inc files to .class.php files so they dont get read as plugins.

First steps toward updating CTools to d7. This contains some stuff found by coder module, plus css.inc should be fully ported. No testing performed though, so theres probably bugs. Need to write some tests or something.

name, they would accidentally share data.

#468120 by jpetso: Incorrectly used variable names in ctools_plugin_api_include caused loss of information.

Add the ability to automatically do .inc files for default objects like Views does as well as more powerful version controls.

Initial commit of content API into ctools. Only one content type is ported, but there are some docs.

Allow plugins to have a process callback so they can modify the plugin directly to provide smarter defaults, plus add some more formal documentation in the advanced help.

Checkpoint checkin: Can now create arbitrary pages! Yay. Task handler manipulation on arbitrary pages works, though there are some clear disconnects in the UI that will be addressed next. Not all page admin functions exist yet (no clone, enable, disable, revert, delete). Not all arguments have criteria yet.

- 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.

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.
