Kiwamu, Stefan

We brought the IMC back to test the new FSS code. It seems to work as advertised - in Kiwamu's words: "fantastic".

First we verified that we can manually lock the FSS, and then engage the autolocker without dropping lock.

Next we verified that that if the temperature is close enough, but the FSS is not locked, the autolocker immediately tries state 2. This trick also seems to work often under normal operations.

Next we locked the MC and kicked it as hard as we could (inverting the fast gain). This triggered the FSS autolocker to drop back to state 2 (with the temperature output frozen), but it came back up to state 4 after 1 sec.
The simple IMC autolocker also seems to work reliably - 10sec after inverting the fast gain, we were back up.

For the temp loop we also verified that the integrator hold in state 2 & 3, as well as the integrator clearing in state 0 works.
