Maslow Firmware Version 0.85

This week's firmware fixes an issue with the machine being unable to load it's position after being disconnected and reconnected to Ground Control which was resulting in a "Please calibrate chain lengths" message.

The issue was that if the machine tried to load it's position from memory before it had been told the specs for the motors it would load an incorrect position, then save incorrect chain lengths to memory. The next time the position was loaded from memory it would be wrong and the machine would try to compute a new position from the incorrect chain lengths and fail.

Firmware version 0.85 fixes this when pared with Ground Control 0.85
