TreeGen Optimization

[tehtelev]

Summary

Added manual position pool and variable for vine positions when generating trees.
An overload has also been added to EvolvingNatFloat, which allows you to compare these objects without converting to object.
This significantly reduces GC pressure, since the code also works recursively.
