Changed SEI_CONF state to resume locking

After a 44 hour lock, the IFO needed some help to keep the green arms locked. The useism has been getting pretty high, so I tried the USEISM state in SEI_CONF and green was immediately able to hold. I changed the default states in SEI_ENV to be the Useism and Useism_Earthquake states, but these should be reverted when the useism is back down.

We have finished an alignment and are up to full power with this change.
