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.
