• Remove Hardcoded TurretHead and Base and add relevant functions to Interfaces for API. Especially in TurretHeadUtils
• Implement Interfaces for TurretHead and TurretBase
• condense ammo consuming method into 1 method, use bases new getInventories() function
• remove hardcoded slot numbers for bases. Instead create a map<int,type> that maps slots to their types
• Add in support to allow modifiying our filterlists for entities via Mod messaging

Closing this, not much refactoring needed for 1.12 anyway. 1.16 will almost be a full rewrite.
