Method to invalidate contraption renderers

- Call ContraptionRenderDispatcher#invalidate, at some point during a tick, and the structure will be reset.
 - Move contraption compartment to SBBContraptionManager
 - Contraption compartment uses custom pair with better hash function instead of apache commons pair
