* New padding approach with separate horizontal and vertical padding
variables
* Improved sizing in large and small buttons and form controls
* Dropped the `.btn-mini` (since we have no `.input-mini` to match, and
holy fuck those were small buttons)
* Dropped the `.pagination-mini` as well because once again, to hell
with such small components
* Changed `@line-height-headings` to `@headings-line-height`
* Removed the `@headings-font-family` because it was honestly kind of
useless
* The navbar is now always 50px high, so no need for that nasty padding
code block anymore.
* The new proposed body padding value also reflects the default navbar's
margin-bottom.
* Fixed the navbar-link example positioning (missing .navbar-text).
* 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)
* Change .brand to .navbar-brand
* Change .btn-navbar to .navbar-toggle
* Redesign navbar toggle to be a bit lighter and wider
* Center align the navbar brand with a max-width of 200px (to minimize hit area) while still centering
* Instead of .divider-vertical, use .divider
* Makes use of .nav-divider mixin
* Dividers are horizontal to start, matching the default state of navbar nav links
* Dividers become vertical above 768px via media queries
* Buttons and progress bars now make use of more semantic global @brand- colors
* Progress bars have been rewritten to reduce the number of possible selectors
* Instead of .progress .bar, it's .progress-bar for individual bars of color, ultimately making for less CSS
