I thought about that.  This is not the only fdo spec that we now,
or might in the future, support.  The other specs may or may not want
to be covered by ecore_fdo, as their specs cover all sorts of different
things.  Xdg also covers all the other fdo specs. I think ecore_desktop
is best, as this code deals with all the .desktop related stuff.

I'll get it in first, THEN worry about caching options.  B-)
