Another overhaul of the whole aggregation procedure. There was an error in the logic which might (probably not, but who knows what our users do with the css?) have accidently removed non-responsive css too.

Overhaul of the new responsive grid CSS aggregation feature. Should be a bit faster and more reliable now.

Removed hook_block_list_alter. We are now using hook_page_alter for adding the debug blocks. This will hopefully fix the probles that we were having with advanced block preprocessing from custom modules.

Fixed a bug in omega.info / Moved the drupal core page elements in the region templates inside of the region-inner containers.

Fixed the CSS for the img tag. Tweaked preprocess_page in alpha. Added a element validator for the primary region setting so that primary regions can only be assiged to zones with a overall sum of region widths that is smaller than the zone column count. Remove _section from the sections in the .tpl and in the preprocessor. Tweaked the overall performance slightly.
