Now using SENSE line from HC-05 to detect a client is connected.
Runs with either sort of HC-05 module, provided the 5 pin regulator style is set to 9600 data mode.
Removed #ifdef BLUETOOTH from .ino file, Bluetooth functions report now anyway with/without client.
Changed "USB" to "DebugPort"
Tidy up of blue wire data frames and passing about by reference instead of just the data buffer.
Added AppInventor application
