[FTC]: Caution - Tetrix Motors burn out on Stall

In case you haven't found out the hard way, stalling a Tetrix motor for even 2 seconds will burn it out.

Be CAREFUL even if you are only running it at 25% power. IF YOU HAVE PID control enabled (RobotC - PID box checked), the PID system will detect a stall and boost the power up to 100%. At which point after 2 seconds, you have a fridge magnet/paper weight instead of a motor.

I ended up making the rule for the team that we will NOT use the built in PID control for the robot. The danger of burning out a motor is just too great. (after burning out two motors, I had no choice)
