Keyboard accessibility in documentation

view) tabindex=-1 in the documentation examples.
Update extend page to point to readme for compiling.

Note that we'll be dropping this page entirely as it's out of date and other compiling options are not recommended for contributing back to the project.
Remove parent div from pagination component

* No more div.pagination; it's now just ul.pagination
* No more .pagination-right or .pagination-centered
* Sizes remain
* Any further customization, such as alignment, should be done on the individual application or site level.
Remove Extend page from the docs entirely

* Information was old and out of date on compiling Bootstrap
* Information was also not directly related to Bootstrap with background info on Less and apps for compiling (Google it, yo)
* Starter template and recommended HTML is already in use on the Getting Started page
