Added support for ACTIVE_TALENT_GROUP_CHANGED

event in Seasons of Discovery
Added timer to ACTIVE_TALENT_GROUP_CHANGED because
direct utilization didn't work as needed
(did not result in equip swap)
Changed implementation of OnEvent function - now
it can handle not only 1:1 events to handlers, but
1:many
