IFO single bounce with fast shutter closed

Vicky and the Squeezers are going to try doing some alignment checks in a single-bounce configuration.  I've left the IFO with ITMY aligned, but ITMX and both ETMs misaligned.  I also shut the fast shutter, and then increased the PSL to 35 W into the vacuum.  This gives us 0.079 mW on AS_C, which is only slightly higher than the 0.072 mW on AS_C when we were locked at 2W earlier today.  So, this should be fine for everything, especially since no light can go to the OMC with the shutter closed.

When they're done for they day, they'll put the IFO back in DOWN.  It won't realign the optics, but it'll bring the power back down to 2W for the weekend.
