Looking at 
http://standards.freedesktop.org/desktop-entry-spec/latest/ar01s05.html 
says the current three types are Application, Link and Directory, and 
that for future-proofing, unknown types should be ignored.

Based on that I think we'd be better off only creating the application() 
provides for explicit Type=Application entries, as types Link and 
Directory are decidedly not applications, and of possible new types we 
obviously have no idea.

Another possibility could be actually emitting a provide for all types, 
based on the value name, eg Link would get a link() provide etc. And 
thinking about that makes me think perhaps these provides should be 
namespaced somehow, eg desktop-application() or such.
