Since we'll be restarting the QUADs (ITMX, ITMY, ETMX, ETMY) again this morning, and now also the Beam Splitter (BS), I've reconciled the SDF system to the best of my ability. 


ETMX 
    - restored to optical lever damping OFF (was ON with a gain of 30)
    - restored ESDOUTF offsets and tramps to zero (left over from charge measurements)
    - ACCEPTED all outputs of existing violin mode damping filters to be OFF
    - ACCEPTED the new L2A filters and gains from Hang's Work a few weeks ago (I'm kind of surprised it wasn't already accepted).

ITMX
    - restored to optical lever damping OFF (was ON with a gain of 30)
    - ACCEPTED all outputs of existing violin mode damping filters to be OFF
    - ACCEPTED new values for misalignment offsets.

ITMY
    - reverted to optical lever damping OFF (was ON with a gain of 30)
    - ACCEPTED all outputs of existing violin mode damping filters to be OFF
    - ACCEPTED a ~100 urad change in R0 alignment offset.
    - ACCEPTED new values for misalignment offsets.

ETMY
    - reverted to optical lever damping OFF (was ON with a gain of 30)
    - ACCEPTED all outputs of existing violin mode damping filters to be OFF
    - ACCEPTED changes to ETMY_M0_LOCK_P/Y to have it's inputs OFF and FM1 OFF, but this appears to be manipulated by guardian, so we should investigate not monitoring these channels.

BS
    - reverted optical lever damping tramps to 20 sec (from 10)
    - reverted having limiters on the M1 LOCK filter banks.

For the ease of recovery, I've also saved all of the alignment offsets for the above mentioned suspensions.
