Fixed a bunch of bugs, added a couple CSS rules to help with other issues as well. Tested with Zen 2.x-beta1 (Woohoo! A beta means less fundamental changes, and less huge code rewrites/rearrangments for me).
Initial release of the Airy Blue theme. This is the same set of files being used on Open Source Catholic, and I don't forsee any major bugs in the code; just missing styles and such. Please post an issue if you find a bug!
