Support for `LoadLibrary` calls

[Midnightific]

This is pretty much the purpose of this fork existing, supporting Overture:LoadLibrary() calls.

We've got a few options to do this:

1. Appending a typeof(require(path.to.library)) at the end of a LoadLibrary call.
2. Transforming the LoadLibrary call to a require(path.to.library) call

The first option is preferable but the 2nd option still isn't bad.
