patches for send.py and RepRapArduinoSerialSender.py

This patch makes send.py case-insensitive, allows specifying baud rate on the command line, adds newlines to the end of gcodes so my arduino knows to send a response, and makes the output more readable.

I've never touched python before, so let me know how this looks

Thanks Triffid_Hunter for posting the files.

I suggest people try these files out and report the results here. If there are no problems, I'll add them to the next skeinforge update.

With this modifications I'm able to print on my mendel with FiveD firmware:
- I needed a \n after setdtr(1) to get a start response
- stripping all spaces from gcode results in quite strange behaviour
- printing what gets really sent
