Invasion Mod v1.2.1

This update of the Invasion Mod fixes a regression and introduces small improvements.

Added the config option mobs-drop-small-remnants (default value: true). If set to false, Invasion Mod mobs will no longer drop Small Remnants on death. (Suggested by @brandyyn)
Fixed [player]'s life is now bound to the Nexus message being shown every 5 minutes (regression in v1.2.0)
Made the Nexus GUI translatable and added German localization for it
Added Simplified Chinese localization (including Nexus GUI) (thanks @M3MEMonster)
Various code quality improvements
Removed an unused debug/duplicate Java class

There are no gameplay breaking/altering changes in this update.
