Waves 1.4

Waves can now interact (push) entities in their paths (configurable, and uses a blacklist/whitelist entity tag system)
Fixed servers not being able to modify the wave data on their end
Moved the wave data configuration over to the configs folder rather than the internal assets folder of the mod by implementing a whole new system
Added block/data caching for many of the necessary logic steps for the spawning of waves, which should improve performance
Did a ton of internal refactoring
