Make Dir return an Iterator of files, not Vec

This is part of work to make the flow of files more iterator-able, rather than going in and out of vectors. Here, a Dir returns an iterator of files, rather than a pre-filled vector.

For now, this removes the ability for error messages to be displayed. Will be added in later though!
