GObject-introspection enablement

[Bastien Nocera]

Heya,

I've fixed gir-repository building, and am currently building
gnome-bluetooth with introspection support.

If you have a library or program that provides introspection, it would
be nice for you to enable it. If you run into any problems, feel free to
poke at people on the #fedora-desktop channel on GIMPNet, or drop a mail
here.

Cheers
