ETMY Damping mode diffs?

Attempting to get the IFO back into observing, but A2L tripped me up with a page or two SDF diffs, which I reverted. Now ETMY shows violin mode damping diffs. I'm accepting them but posting a screen shot of the changes, so someone who knows the whys can check.

These filters should be turned on (alog22816). If unable to get out of Observing mode to turn on the gains please keep an eye on 1008.45Hz line and make sure it's not ringing up.

To clarify, we have been reverting these gains.  Guardian doesn't turn them on (Nutsinee/Evan: should we have Guardian just do it?), but we have been turning them on by reverting the gains to the non-zero values that SDF has. 

Next time we are about to go to Observe, we should put these gains back to their non-zero values, and accept them in SDF.  NB: They should be zero while we're locking, and can be turned to their non-zero values any time after the BOUNCE_VIOLIN_MODE_DAMPING state.

Jenne, Nutsinee

We just put this in the guardian code. Since the set points of 0 have been accepted next time SDF will show the difference. Please ACCEPT the new EPICS values for ETMY MODE3 and MODE9 gains.
