The Xarm green WFS were struggling a bit during re-acquisition this morning, so Sheila tried enabling the TMS WFS as well as the usual ETM WFS in the LOCKING_ARMS_GREEN state.  This worked well, and she has previously also had it work for the Yarm, and has made a guardian state to do this in the ALS_ARMs. 

I have now changed the ALS_ARM guardians to use the 2 WFS version (ETM and TMS) in the main path, and the ETM-only version is now on the side branch.  This also required a change in ISC_LOCK guardian to request the 2 WFS state. 

So far, we're still on the first acquisition with both green arms using both ETM and TMS WFS automatically through the guardian, but it seems to be working so far.
