please test thunar - 1.8 from COPR

[Mukundan Ragavan]

I have been working to update thunar to version 1.8 on Fedora rawhide.
Since this is a GTK-3 build, I created a COPR [1] to test if everything
builds properly.

I now have the relevant packages built and things should work fine. Can
folks running **rawhide** give this a spin? This is going to be rawhide
only.

Needless to say, treat these builds as *test* builds and take all
appropriate precautions.

Thanks,
Mukundan.
