* 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
I have recently been experimenting with a lot of Typeahead controls, and I ran into a situation where my Typeahead was too wide for my screen, particularly on mobile devices, and it was not wrapping as I had expected it to do.
http://jsfiddle.net/Mtxkn/3/
Changing the CSS for `.dropdown-menu > li > a` to `white-space: normal` causes it to wrap in every scenario that I have seen, whereas leaving it as `nowrap` never does what I want when the text is too long for a given row.
It's possible that this has ramifications for other dropdown menus, but honestly I expect that even those would prefer to wrap than to extend the screen horizontally. If that is not the case, then it would work to change the typeahead version of this only:
```css
.typeahead > li > a {
white-space: normal;
}
```
