Android Progress

Posted a quick update to GasTrip that fixes a bug in the MPG selection interface.  It should now show the correct MPG when selecting to pick another one.  Still hard at work on other updates, but work that I get paid for has to take precedent, unfortunately.

After receiving initial feedback from my initial release, here are the planned updates that are currently in development.  I will publish an update sometime early next week.

- Allow user to manually enter price of gas
- Show multiple gas stations and prices in the area
- Enable Gas Trip to run in the background to keep the total updating when not the currently active screen.
- Prompt to turn of GPS when not in use
