Issue #1230786 + Issue #1231160: Fixing content_attributes_array in hook_preprocess_node & fixing incorrect 'There are no unassigned regions' on the theme settings UI.

Regions custom css has to be named wrapper_css instead of css to be applied to .region instead of .region-inner.

We are now aggregating all grid information in the new theme container aswell for even better caching.

Major overhaul of most of the code. Removed preprocess/process folders from core to increase performance.

Slightly improved the equal heights code. It now supports custom min-height / height in your CSS for the targeted elements. This is useful if you want to give your elements a specific min height.

The equal height feature is now based on jQuery again but the code was rewritten. It is now based on a jQuery library from Ben Alman. This should even work with expandable textareas / fieldsets and basically everything else that might have an impact on the height of a single element in a group.
