* Bring back the navbar up top
* Pull the docs content back into separate pages because a 6.6k line docs file is just crazy
* Recenter the page content and bring back affixed side nav (needs work)

* Add new grid mixins adapted from Preboot (http://github.com/mdo/preboot)
* Drop the @grid-row-width and @grid-column-width variables
* Add the @grid-float-breakpoint variable, as used in Preboot
* Add support for .push* and .pull* classes for column ordering manipulation
* Document all the things

Mini typo fix in the docs...

* Remove .input-mini because who really needs inputs that small
* Remove unnecessary border-radius resets from large and small input groups

* Same code, but different classes was confusing
* Now .img-thumbnail just extends .thumbnail
