This is a customization of the nav bar to try to make
things a little more navigable.  This isn't really approved by (I copped the basic idea from the Subversion project pages),
but it works for our purposes.

The main changes are:

* Added links to the home page and wiki.
* Our custom issue tracker page, which contains common queries.
* Subheadings for reporting a bug / submitting a patch / request a feature.
* Link to our Roadmap page.
