Medulla will freeze if encoder communication is interrupted

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Turn on the microcontroller
2. Unplug an encoder

What is the expected output? What do you see instead?
If the encoder cannot be read, a second read should be attempted, if this fails 
then reading the encoder should be skipped. If encoder cannot be read several 
times in a row, then the medulla should throw an encoder error and estop.

Currently, the medulla will get stuck in a loop until the encoder can be read 
correctly or the watchdog timer triggers.

This is now fixed. The medullas will no longer freeze when encoder comms are 
interrupted.
