Complete python strip chart code

Major Addition: DataPlotter.py
1)Working python code that reads in encoder, current and state
information from the gibbot and graphs it in a strip chart
Next steps: create a gui through which one can select which information
to graph and send commands to the dsPIC. Also, there is a minor
aesthetic bug during the section before the graph translates to the
left.

Minor Edits to BLDC interrupt code: 1) fixed while loop in interrupts.c
2) added code that transmits encoder, current and state readings in hex
