Scripts/Quests: Fix Quest A Spirit Guide

- 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).
