Mahou Tsukai

- fix bug where weapon projectile bow had no durability
- added durability config, projectile speed config, and damage multiplier config for weapon projectile bow

- reimplementing POWER_CONSOLIDATION_RETRO_FOG_FIX to handle lake tiles that were previously tile entities but are no longer tile entities. if you have a lake in your world with no fog, and it bothers you, set this to true, then load all the chunks with murky water blocks in them. then turn this off because it will slow down new worldgen unnecessarily. or you can just remake the lake.
