Added a brand-new Drush command called "drush omega-wizard" (drush owiz) that allows users to create subthemes through a Drush wizard. This allows people who do not know the syntax of "drush omega-subtheme" to conveniently generate themes with the same power that the "drush omega-subtheme" command offers.
Fixed a bug in omega_discovery() that caused sub-themes to not be able to override base-theme definitions.
Quick follow-up for 7.x-4.0-alpha3 that fixes a problem with compatibility checks for extension dependencies making it work with development versions of modules now as well. Also, it appears that the theme function include files were named incorrectly all the time.
This beta release fixes several known issues, and adds several new features.
Updates to beta2 from beta1 should be painless. At the most, if you have your content region ordered visually differently than the HTML order, you may need to adjust some settings in the UI to get them to render properly again.
