Removed the landscape-only constraint on APSelectionActivity and moved it to JoystickActivity.
Logging (0,0) when resetting the joystick head.
Modifying the max db threshold
Slightly changed the layout settings.
 - fixed menu->refresh, it now triggers re-scanning access points...
 - restarting the timer when CONNECTING message is received. This fixes the problem of two-click robot connection when the first click fails while robot connecting because of a timeout.
 - stopping the robot service as a first step of trying to connect to an AP
 - disabling/hiding the activity title.
