Merge pull request #43 from PedalPDX/clipping

Adds basic clipping to app
Set how much to clip from the route in miles by clicking the clipping button on the start main activity screen.
After finishing a ride, you can see the unclipped map by pulling up the menu and clicking map.
The clipped map, made from the same points sent to the server, is accessible from the menu on a ride's details page.
