Major changes to the .info array for css support. Also added library support for adding js and css in a bulk. Added caching to the css and library registry. Added a default styles.css to every starterkit.

Added mobile.css to starterkits and renamed the keys of the optional css files and grids in the base themes (alpha & omega) with preceding omega_ / alpha_ so that we dont steal the namespace from the subthemes. / General cleanup.

Finally converted (almost?) everything to be using  instead of  and . Some code cleanup. Adapting the code to our initial concept (alpha needs to say clean and lightweight) and therefore moved some of the preprocess / process code to Omega.

Added support for disabling / excluding core, contrib module and theme stylesheets[] definitions via the Omega / Alpha theme settings

adding default text.css to Omega, setting up Alpha with a first pass at rendering the faked branding block; needs review & refining

removing the setting for render traditional search box as it was no longer used in preference of the block
