Title: [2.0-wip] Added dropup support to split buttons and navbar

This commit extends the dropdown-menu classes to create a new dropup component (using a previously undocumented ```dropdown-menu.bottom-up``` class and brand new ```dropdown-menu.pull-right``` class.)

* Documents the hidden .dropdown-menu.bottom-up option (to be used for dropups)
* Extends the .bottom-up class to carets and all relevant caret styles
* Adds .dropdown-menu.pull-right class for right-aligned dropdowns and dropups
* Adds examples and some information to the "split dropdown" and "navbar" sections of the Docs

I paid special attention to the carets, especially in the navbar.

I also documented the new dropup feature and added some examples.

TESTED with Google Chrome 17, Internet Explorer 8 and Firefox 9.01 on a Windows 7 machine.
