Multiblock handlers are now objects. Added pre-destroy handler for satellites, which initiates invalidation of the whole structure. Need to guess why a separately stored meta is set to -1
Packed disposal marks, stored meta and state into flags. Added accessors. Switched dispose method to check against Alive state - so it won't recurr into invalid TEs
Overworld endpoint is deconstructed into its original components instead of junk. This is temporary. Also exit search algorithm is separated from general assembly code - so it will be easier to make good search algo
Sketch for lookup algo. TODO: endpoint rating func and distance/rating based sorting
