* Added a new mixin to calculate rems and pixels for IE fallback
* Updated the body, p, and .lead elements to use the new .font-size() mixin
* New mixin has default value of 14px or 1.4rem
* Still needs exploration, and change this means lots of work rejiggering margins and line-heights
* Related, started to reorganize the mixins a bit to call out mixins that are used by the framework and not utilities or snippets
* Uses .btn on label elements with nested checkbox and radio controls within
* Updated examples to reflect change in HTML and CSS
* Had to add .active all buttons for proper state highlighting (mimicing the :active pseudo state)
* Still needs JavaScript plugin updated by @fat
* 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
Buttons that are disabled are still clickable and can still fire click events (such as hopping up to the top of the page if your anchor href points to "#"). Adding the pointer-events:none property will truly disable the button so situations like this don't happen.
* 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
* They're hidden by default in the mobile-first views because otherwise they just cover up the slides
* In mobile they're centered, and then are shown left aligned at larger viewports
* Drop custom type arrow controls for glyphicons icons instead for more consistent rendering
* Remove the captions and instead let folks implement what they want in the carousel
* Move the indicators to the bottom middle instead of top right
* Lighten up gradients on the edges for less harsh lighting
