Added tracking of Priest's Evangelism/Archangel stack & duration

Functionality: Display time remaining of Archangel buff (5-25% extra heals). When not found, display time remaining & stack count of Evangelism.

Apparently I was half asleep when I wrote that comment ... Anyways, I hope this is the way to do this - and even if it's not how you intended SelfBuffAliases ... it does work :)
