TODO: Implement connecting to a different GameTile after you have connected to one.
Added pragma TODO markers
Added refresh functionality for a Complete implementation of Bluetooth

Changes:
- Changed ARMBluetoothViewController to subclass UITableViewController

view.
- Fixed issue #15
Closed issue #8: Copying bundle resources to documents directory at application launch.
 - Done in TestAppDelegate.m in function application:didFinishLaunchingWithOptions:
Fixed issue #20: User image wasn’t saved to the documents directory
Changes:
	- ARMPlayerInfo implements a new method: “bluetoothDidConnectGameTileWithName:imageTargetID:” that the bluetooth manager will call when it completes the data transfer with the game tile.
Fixed issue #21
Changes:
	- Remove all images other than the default logo image at application launch
	- Bluetooth manager sends “bluetoothWillConnectToNewGameTile” when the user chooses to connect to another game tile, and ARMPlayerInfo deletes the previous stored image file.
	- GameServerCommunicator records its files when it downloads them, and deletes them when the “leaveGameSession” message is sent.
Fixed Issue #19 Sometimes Bluetooth errors surface to the user
Changes: A default error message is displayed for unexpected errors, and the errors are logged with NSLog.
