fixing css issues in 960-fluid.css, using hook_css_alter to add the fluid css now rather than trying to overwrite default 960.css, also fixed issue with search grid width on the themed version of the search form.

adding support for alternating settings for content zone on front and internal pages, fixing css issue with alpha/omega

final changes for a simple, D7 working version of Omega. region settings, general preprocess working perfectly

adding DRUPAL7.txt for outline of changes & issues with theme upgrade to D7, changing basics so theme will be allowed to be enabled to start debugging upgrade.
