NPC improvements
Currently still a WIP, this fixes a lot of typos and inconsistencies. The goal is to ultimately at least finish fixing all the Candor NPCs and maybe even a few Tulimshar ones. Another goal is to reduce the amount of strings and potentially optimize other things.
Changes that need explaining (will be expanded with more commits):
- I removed the honor system explanation from the trainer NPC since there is no pvp until you reach Tulimshar. Quirin already explains it as well, so this is pointless duplication.
- I did a lot of rewording/rephrasing to have more variety in the responses.
