Subject: [PATCH] Support long file paths on Windows (past 256 limit) (#464)

* Support long file paths on Windows (past 256 limit)

This issue can occur when using symlinks deep in rojo such that very long paths can occur, among other scenarios.

Note while the original fix comes from here:
	https://gal.hagever.com/posts/windows-long-paths-in-rust/

The manifest had to be modified from this source:
	https://stackoverflow.com/questions/59816045/windows-10-1903-longpathaware-not-working

* Move manifests, tidy code a little
