Merge Arduino code to run BT without Accel

-Introduce new #defines
//#define DEBUG
//#define FREEFALL_MOTION_ENABLE
//#define BLE_FIRMATA
#define TEST_BT_WITHOUT_ACCELEROMETER
-To run BT+Accelerometer together, comment out this feature
TEST_BT_WITHOUT_ACCELEROMETER
-We might not need the BLEFirmata code base for the Arduino prototype
-Just one file
Merge branch 'Arduino-Code-Cleanup'
