Change use of "content" div to "pane-content" and "title" to "pane-title" to prevent conflicts with other things that use these fairly generic classes.

Clean up caching of displays in page manager. Still need to do mini panels and panel nodes, I suppose.

Added allowed layouts to settings form for panel pages, nodes, minis.

Fix panel page type to actually respect the contexts.

Break panels_node_content into a module + a .inc file to more clearly represent how content types can work in a module. Also fix several notices by providing defaults for the form.

Add a new directive to content types to allow fetching information about a single subtype (i.e, view, block) rather than all at once.

Introducing the new version of flexible which is both more powerful and comes with a javascripty visual layout designer. It is not yet flawless but it finally works well enough to commit. This commit REQUIRES the twin commit of ctools that is going in.

Improve styles and flexible layout with css caching and moving the rounded corner style fully into its sub directory.
