Duplicate()

[nathanrw]

I want a convenient way to duplicate entities.

At the moment you need to call GetAllComponents(), which is unsatisfying.

This implementation is faster, and could be made more efficient in future.

On my (rather old) computer (N=10000):

Method	Mean	Error	StdDev
DuplicateNInternal	8.099 ms	0.3745 ms	1.0438 ms
DuplicateNDuplicate	8.874 ms	0.3976 ms	1.1662 ms
DuplicateNGetAllComponents	31.285 ms	0.5823 ms	0.7971 ms
