UI Scaffolding

Converted MapActivity to DrawerActivity with a MapFragment.  Note that the drawers are not in the action bar until DrawerActivity is opened.

Note: I'm not sure which IntelliJ files are safe to remove from the repo yet (I tried a few combinations all to no avail).  They will likely remain until the 4.3 SDK update.  So just ignore them in this PR.
