Title: Replacement for system.file

This inserts a replacement version of `system.file` into a packages _imports_ environment. (This actually works out to be a lot cleaner than inserting it into the namespace environment.)

It could probably use better documentation in `load_all`, but otherwise I think should be good to go.
