Following from last week (alog81493) I've now replaced the Increase_Flashes (IF) state calls with SCAN_ALIGNMENT (SA). The former still exists, I've created parallel paths in the ALS arm nodes, but it's not called by ISC_LOCK or INIT_ALIGN. If there are any troubles, then reverting ISC_LOCK and INIT_ALIGN should be all that's needed (no need to touch ALS nodes).

Last week I wanted to return the functionality to immediately stop if it sees a flash above threshold. I added this back in, but since it has to watch slow channels, it rarely happens. Still though, SA seems to be slightly faster than IF, accuracy seems similar.

I've also added some more fault checking and a way to "gracefully" escape the state. I would still like to go through and clean up the code a bit since it's currently a Frankenstein of comments from me integrating this. This includes some log and notifications that might still reference IF. For other time.
