Small Fixes and Tweaks for Awakening and DLC

Here are (currently) 5 small mods to fix or tweak some Awakening or other DLC stuff.

First is replacing the Knight corpse in Wending Wood to an actual Elven corpse. He uses vanilla items.

Second is fixing some DLC codex. I've removed pointless credits to now be more informative about the world. All are official and canon, taken from other DA sources.

Third is putting the Blackblade Boots and Gloves in the same chest where the Tunic is and removing the rogue restriction from them.

Fourth is updating the Varterral's codex from Witch Hunt with the text from DA2.

Fifth is making Nathaniel able to be recruited immediately after you tell him to go. Requires Awakening Encounters Renovation from Shanamah.

No known compatibility issues. All can be put in Documents\BioWare\Dragon Age\packages\core\override. And if not needed anymore, can be removed.
