Allow components (other than brand and toggle) to exist outside collapse within navbars

Chrome on Mac. Comparisons between WIP and RC1.

Please allow components (specifically a right-aligned dropdown menu) to exist outside of the collapse within navbars.

With this it is relatively easy to create the common 3 component (toggle, brand, [random component]) navbar layout that seems to be popular in many mobile sites and applications. This was very easy to do in RC1 and required only a minimal amount of additional styling but attempting this in the WIP version is quite a mess, especially with the navbar-header requirement.

Here are jsFiddle examples of this layout:
