CAN periodic status

[mjcoss]

Since we use C++, I didn't even know that there was such a feature. I've added checks to each of the various classes that use the CAN bus and Jaguars to query the Jaguars for reset, and faults after are update operation on the Jaguars. At least this way, I can determine if something has gone wrong..assuming the Jaguars are replying

It's a bit of traffic on the bus but I see no alternatives, other than getting rid of the Jaguars
