Core/WorldSession: Added research notes about CMSG_AUTH_SESSION values and reordered checks during login to always initialize encryption first to make sure the client can read failure packet
DB/Misc: Various Frenzyheart/Oracles Chain fixes

* Rescripted Injured Rainspeaker oracle and both Just Following Orders and Fortunate Misunderstandings and works properly now ie when you find the injured rainspeaker oracle you find lying on ground, you select gossip option to pull injured rainspeaker oracle to his feet crocodile attacks, once crocodile is killed Shaman Vekjik turns up and says a few lines
* New waypoints for a Rough Ride from sniff, the crocofile no longer goes through texture but camera is still glitchy
* Mosswalker victims will now summon mosswalker pocessions if the event of them deciding to die while doing the mosswalker saviour
* Correct text for softknuckle matrat for when summoned
* Spawn Shaman Jakjek and Lightningcaller Soo-met and phasing for these, however phasing does not work exactly as should do as you should only be able to see these two npcs while you are working towards that faction but since quests stay rewarded even after you change faction there is no way of doing this using quest and spell area is limited, there are two faction choice tracker quests (hidden) for wolvar and gorloc and spells which add this quests to player but also once these are rewarded they stay rewarded.
