Colored JTextPane logging for Drawbot, minor updates

– changed manual driving buttons. “centered” now says “this is home” and “home” now says “go home”.
– changed log window so text is colored for better readability.
– disabled the paper config and the machine config until the robot is connected.
– fixed a bug where configuration was not being sent to the robot, which screwed up all movements.

I really hope I can get limit switches working soon. Then I can auto-calibrate, which means less configuring for you.
