#427666: Provide the right theme path so Views can display the views-view.tpl.php template for the panel pane.

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

Allow restricting contexts via access control to allow the add content UI to remove irrelevant content.

Expand the context to allow the plumbing for replacing placeholder contexts with real contexts for preview.

Implement context keywords which also use the converters. Add converters to user, fix taxonomy converters.

Remove the setting to allow Views to use the exposed form as that isnt actually implemented. Would be a nice feature though.

Do not force panes to fail just because subtype does not exist. They may want to render something anyhow.

Fix the "save" button to work on the views content settings page, though that page is still in the wrong place.

More robust AJAX stuff that will eliminate some ugly errors plus prevent double clicks on ajax links.

Port block content from Panels, reorganizing them so that the categories are more what the content is about than where it is from.

Integrate the default form (title override + context selection) with the first step in the pane config forms.

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

Updates to smooth out problems with the new panel page type, remove deleted displays properly and other fun fixes.

Make access plugins a little less focused on the term "access" and change selection criteria to selection rules.
