Tweaking BS ISI ST2 boosts

Back in October, I had worked on the BS St2 boosts to try to reduce locklosses caused by engaging the ST2 loops. I had noticed a few times that we still got kicks here, and I had a lockloss earlier today. I reduced the ramp times on the boosts for the X Y Z and RZ loops to 2 seconds, from 3. The last couple of DRMI acquisitions have had this change running, and I haven't noticed the wiggles in DRMI that I was seeing before. I'll try to get a more detailed look, after we get locked again.
