Make FileSource capable of handling resource files.
Without this, we failed to open the silent resource file used as a placeholder
in templates and thus failed to replace it with the proper file after loading
the template -- the consequence was that (although the right audio file ended
up being shown as the main model) any derived models were not regenerated
