Style tests and class cleanups

Sorry this is so monstrous...

It's a heavy clean-up of the CSS/LESS classes and such. The prime objective was to get things focused on using Bootstrap 2.3.2 styles vs. custom stuff or ad hoc re-styling.

There'll be more of this stuff needed on an ongoing basis to keep things clean and more easily upgradable to Bootstrap 3 when that time arrives.

Thanks!
