CHANGED:
- circuits are no longer held in history for a given amount of time. Now, only the last xx (1000) offline circuits are held in memory. This offloads the stress from the POE framework (especially if there are lots of items in the list)
- added an option to remove state files on disk from /offline when a circuit is removed from history in CM
- removing alarms which were set on events which won't happen anymore (like Lifetime timer/alarm if a circuit is taken down prematurely because of transfer failures)
- various other small bug fixes
