3.3.5 - A Spirit Guide (Issue 4028)

Hopefully I'm doing this right.

This change along with https://github.com/Trisjdc/TrinityCore/commit/718ca32f7e2210c6ce3178801a862f02cd3956d9 (he never made a pull request it seems) will resolve the quest problems entirely.

I'm creating a pull from his commit also (if it'll allow me). 

Breakdown of changes from THIS pull request:

 - Ensures rep adjustment buff is always applied (overrides evade, implements existing evade + re-apply buff)
 - Removes un-owned ravagers with incorrect faction from DB (the correct ones are spawned with their masters without the DB entries)
 - Create some extra steps in the wolf's waypoints in order to generate some AI events for the Ryga NPC. I think it's a bit of a dirty solution, but it seems to work with minimal changes.
 - Created RP series of events with Ryga NPC and Ancestral Wolf Spirit (Ryga Kneels, talks to wolf, then returns to spawn position after around a minute).
