Added drawable backgrounds for custom start/stop buttons
Added theme support
Adjusted min sdk to support theme
Initial import of activity and fragment handling classes
Initial commit of ui layout files
Initial commit of dummy content for lists
The new UI has now been fully merged. I have moved the "core" of the
application into the RouteDetailActivity. Right now, this handles
updating the timer. I have not properly implemented onSuspend and
onResume yet, but the demo works properly so far.
