Revert some of the responsive UI stuff for now

[markjaquith]

It didn't test well, and wasn't quite what we'd discussed. Keeping the menu collapse, but most of the other stuff should roll back.

Tasks:

1. Eliminate the "auto" columns setting and have it funnel back to previous default.
2. Adjust CSS on cats/tags pages.

In my experience, having used 3.3 for a few weeks now, the "auto" feature has actually worked quite well. What's the reasoning to rolling it back?

Sorry if I missed an already-had discussion about this.

It didn't test well. Wasn't what we wanted. It was discussed in the weekly chat today.

Yeah, it worked well for smaller screens (iPad, etc.) but not that good for very large screens 2560px+ width.

After [18889], Dashboard starts loading with 2 columns, but then switches to 3 columns (1440x900), regardless of the actual selected number. 18863.3.diff​ fixes that.
