Brian Murphy 89dd5e2599 Move alert execution out of scheduler thread.
This commit moves the execution of the alert trigger to the AlertActions queued thread.
Also change the states of AlertActionEntry to include SEARCH_NEEDED and ERROR and remove now uneeded states.
AlertActions now take a TriggerResult instead of an alert action entry.
