Topbar Prototype

Disclaimer: This is just a PREVIEW...I dont yet want it pulled in at this point. 

I just wanted to start the discussion of a common topbar that 

 1. Integrates well with fauxton
 2. Is highly configurable, with default settings, settings passed in from one app as a bootstrap, and finally couch wide settings.
 3. Has a common sync metaphor with the bundled pouchdb.
 4. Acts as a gateway for installing other apps.
 5. Can be reused in other apps, for consistency 
 
Yes, it's ambitious!
