Te-Wei Tsai has is changing the main telescope camera rotator low level controller to transition from FAULT to STANDBY when it receives the clearError command, instead of to OFFLINE/PUBLISH_ONLY.

I hope and assume he plans to do the same for the low-level hexapod controllers.

Update ts_hexrotcomm, ts_hexapod and ts_rotator accordingly:

• Update the mock controllers to transition to STANDBY instead of whatever it presently transitions to (probably OFFLINE/AVAILABLE).
• Update (probably remove) any comments that describe the old behavior.
