nautilus gio-branch merged

[Alexander Larsson <alexl redhat com>]

I just merged the nautilus gio-branch.

Its still kind of raw, but its time to get some more testing and
feedback.

Most things work, but not everything. I don't expect to make a release
until a bit more things work, but I want to get this out so that we get
a bit more testing, and hopefully a bit more developers interested in
helping out.

I added a GIO component to the nautilus bugzilla product, please use
this for bug reports.
