edl: accept arbitrary paths

Until now, .edl files accepted only "simple" filenames, i.e. no relative
or absolute paths, no URLs. Now that the origin bullshit is a bit
cleaned up and enforced in the EDL code, there's absolutely no reason to
keep this.

The new code behaves somewhat similar to playlists. (Although playlists
are special because they're not truly recursively opened.)

-``edl://``, while ``.edl`` does not. This makes no sense.
