Beak for iPhone (navbar redux)

Okay, finally got a navbar UI that I'm happy with. I'm implementing a horizontal scrollbar at the top so you can flick through to the various views (Settings is hidden on the left, Favorites is hidden on the right, and a bunch more will come into view once you scroll either way.)

Some of the icons are tweaked from Glyphish & are styled to look like normal UITabBar highlights.
