ETMX 18kHz MODES added

Jim W., Jeff B., Terra

We've used the earthquake down time to add the following modes to PI damping:

MODE 19: 18041 Hz ETMX and MODE 21: 18061 Hz ETMX

Both are now fully set up in the PI MEDM screen, receiving error signal from OMC and driving ETMX. Both do NOT have a gain auto set to turn on (so will send zero drive); these modes haven't gone unstable in the past month or so but should be watched and if ops/commissioners find it best to set a gain, we can add that to the SUS_PI guardian. Jeff has added these modes to PI2 StripTool though can someone make sure they show up on the front wall StripTool?

    I added the new modes 19 and 20 to the PI2_monitoring.stp StripTool. The nuc6 screen has been reloaded with the new modes.
