Thanatos

This version mostly is a rework of a couple things to make mod compatibility better by default hopefully, as well as cleaning up code in general. However, there are some features too.

• Changed range of Respawn Inhibitor from 128 to 64 blocks
• Made it possible to have the mod be enabled or disabled by default for new players with a gamerule
• Implemented #2 part 1 (Added a new system for death animations with the mod, actual death animations will be in the next version)
