add fixes for region area ajax building twice, still haven't figured out why ajax is slow on firefox

add fix user page missing blocks especially on /user/xx/edit path due to sigmaone thought that path is considered admin path process all blocks as admin theme which breaks the front end blocks

Fixed bug plugin user profile - if turned off throw fatal error from drupal_attributes cant process empty string

fixed mediatable show double listing, added new code to mark first 3 column as essential so it will be shown when the view port is small

added feature so now theme can use vtcore_alter_process hook from template.php, add new array key for vtcore special blocks

Removed  sigmaone_breadcrumb() function, in favor of direct rendering breadcrumb from block renderable array as a markup - Clearing cache Required for user updating to this new version
