Make exo-open more standalone (bug #6573).
Not all file managers support file locations, so instead
try other launch methodes first. If not category is supplied
in for exo-open we try to following steps:
- Known uri for preferred apps (mailto, http(s), ftp(s), trash)
-> launch through exo_execute.
- File type is a directory
-> Launch through exo_execute as a file manager
- Lookup default application for the content type
-> Launch it
- Fallback to gtk_show_uri()
-> Who knows what others find.
With those steps we also bypass most of the GIO module, which
is not going to build with glib 2.27 anyways.
