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

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.

be the perfect solution but the jQuery approach that we were using before proved to be
a dead end.

Fixed alpha_invoke to work even without function names. Also the media queries javascript library now adds a body class depending on the current layout in charge.

#1186924: Set min-height to 1px for .region in alpha-debug.css so that empty regions don't collapse weirdly when toggling off the debugging blocks with the JavaScript button. Also added some stuff to the previous patch for the jQuery media query solution.

Issue #1184546: Merged the zone and region configuration tabs into one single tab and made the zone and regions collapsible fieldsets.

Reroll on the equal heights script... We cant make assumptions like that sadly.. For now subthemes need to cover the resize event.
