Partial implementation of leadership in raids

Currently working: stat bonuses and client side only effects
Currently not working: Mark NPC and others that need more server side work

Currently only tested on UF, Ti and 62 may work, but not tested
SoF, SoD, and RoF need packet translators, which are most likely the same as UF
