Title: Added "dropdown-header"

Updated the "nav-header" class to "dropdown-header" to move inline with Bootstrap 3 RC1 classes.

Retained backwards compatibility for anyone who has "nav-header" in their existing menus which will output as the new class name. Backwards compatibility to be remove upon official launch of Bootstrap 3
