Lots of new optimizations utilizing prepatcher

To start, this mod now requires Prepatcher and Fishery. New optimizations include: gene ticking improvements, world object improvements, hediff optimizations, world pawn gc optimizations, better mothballing, dds support, ContentFinder caching, additions and changes to reflection caching, as well as various other additions. Multiplayer support has been improved too, but should be considered highly experimental. The WorkGiver_DoBill bug is fixed in this build. Multiple patches aiming to improve RimWorld's load time have been added too.
