* 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
* Remove border-radii on top of tab dropdown menus
* Remove the .dropdown and .dropup styles and instead place on all
* Use on dropdown carets intead of separately applying margin with a top alignment
* Some other misc cleanup
* Instead of 20px as @line-height-base, use 1.5
* Update typographic scale for headings to use unitless as well--required some twerking of decimals a bit and some rounding
* Introduce new @line-height-computed value, which takes base font-size and multiplies it by 1.5, for use in padding and margin on components
* Refactor the .forms-horizontal code--much simpler now and built on the Bootstrap grid system instead
* Remove all the margins on form controls for simpler styling everywhere else--was overriding that way too often
* Drop .help-inline, but keep .help-block
* Drop the unused input grid class overrides
* 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)
* Overhaul the form control sizing section to only show sizing via grid columns as parents, not as classes on inputs
* Restore the inline-form option
* Restore the bottom margin on form controls and make them block level instead of inline-block
* More misc docs cleanup for forms
* Instead of , use for standard, gray button
* Improves ability to customize buttons by encouraging folks to not override .btn and thus overriding all button modifier classes
* Updates docs to reflect the change
* Reorganize buttons CSS
