Merge pull request #47 from RitwikGupta/master

Added arrows and fixed checking for bus routes
Changed the icons of the buses, made sure the UI doesn't run in the background (with timertask), button click of the list instantly updates the UI and resets the timertask, saved camera location.
Added slightly more documentation to the request task.
Added even more documentation and attempted to pass the activity through the thread... couldn't? not sure...
Made todos to look into hashmaps
Added a debug apk folder in the project file for alpha testing.
P1 icon got lost in the crossfire so had to bring it back from the dead. Also map didn't clear if the listview was empty so that's now fixed too.
