Fixes #71
Basically, we already implemented separate random seeds in the editor, but it only works right now because our example code happens to not use any runtime random number generation. We need to have any internal functions that use random numbers capture the generator when constructed, and then use that at runtime.
In the future when implementing #52, it will also need to use the pattern of saving a reference to the current random number generator in the constructor.
