TMTS channels added to DAQ

Per a request of Jeff K, I made an additional update to the TMTS_MASTER.mdl, to add DAQ requests for the 6 ...M1_DAMP_*_IN2 channels. I then rebuilt and restarted h1sustmsy.mdl.

In the process I noticed that there were error messages being generated from the following lines in the safe.snap (these may have been there yesterday, see alog 6883, but I don't recall), so I manually edited the file and removed the second half of each line.

H1:SUS-TMSY_M1_DAMP_P_STATE_GOOD 1 H1:SUS-TMSY_M1_DAMP_P_STATE_GOOD 0
H1:SUS-TMSY_M1_DAMP_R_STATE_GOOD 1 H1:SUS-TMSY_M1_DAMP_R_STATE_GOOD 0
H1:SUS-TMSY_M1_DAMP_T_STATE_GOOD 1 H1:SUS-TMSY_M1_DAMP_T_STATE_GOOD 0
H1:SUS-TMSY_M1_DAMP_V_STATE_GOOD 1 H1:SUS-TMSY_M1_DAMP_V_STATE_GOOD 0
H1:SUS-TMSY_M1_DAMP_Y_STATE_GOOD 1 H1:SUS-TMSY_M1_DAMP_Y_STATE_GOOD 0

Chris Wipf then reported that sometime in the last few days, the setting for the alignment offset gains in the safe.snap had been reset to 1 (whereas they are supposed to be magic numbers that convert mrad of desired offset to counts of actuation). So I transplanted the following lines from an hourly backup from 6/20/13:

H1:SUS-TMSY_M1_OPTICALIGN_P_OFFSET 1 -8.950000000000000e+01
H1:SUS-TMSY_M1_OPTICALIGN_P_GAIN 1 1.583586000000000e+02
H1:SUS-TMSY_M1_OPTICALIGN_Y_OFFSET 1 1.899000000000000e+02
H1:SUS-TMSY_M1_OPTICALIGN_Y_GAIN 1 5.171050000000000e+01

The updated master model and safe.snap have been committed.

This first error probably happened after the snapshot update I made for the "STATE_GOOD" channels of every suspension with a generic script (cf aLog 6813) and the second  because I didn't update the safe snapshot after applying the changes to the TMTS alignment offset gains (cf aLog 6749)
