Quick bug fix with the Simualted Lighting expansion

The SimulatedLightingExpansion's Flashlight transform had a bit of a problem where it was trying to use a function that wasn't included in the original package-- That's my mistake.  I have a file containing utility functions, such as the getMouseX and getMouseY functions that I did not include in the package, but was still declared in my testing project.

Thanks Requiem for finding the problem!
