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

variable_get was being called 10s of times in alpha_invoke on the theme load. Saving  as a static variable reduces the variable_get calls down to one on theme load.

adding default css resets for core; updating theme settings ui to wrap zones & regions inside their section container

Tweaking the regions preprocessor to exclude 'artificially' created regions which are not part of alpha

Added viewport scaling support. Primary regions now consume the empty column space in a zone - Visual ordering for primary regions doesn't work yet

Now all DEFAULT grids have the proper debugging images for 12, 16 and 24 columns. Also removed a minor bug with the inline CSS

Came up with a concept for debugging the different column counts: Inline CSS. Since we only add it for debugging purpose noone has to worry about it actually being inline. It also makes the rest of the code faster (when not in debugging mode).

Adding the proper .png for 24-column normal grid and fixed a bug where the optional css files didnt show up in the admin UI)
