AlphaBot... REBUILT

Big overhaul.

Removed all traces of accelerometer, will go back to get it if we need it.

Command parsing all done through switches now. Much easier to read.

a 'library' of commands and functions now exists to make adding new functions a little easier.

Removed the need for an initialization command. thought it would help with the serial read bug, but it didn't. Will still need to find a better solution. Might need carriage returns mandatory. Will investigate.

The new program is quite a bit lighter. More space available now on the board.
