GNOME Boxes 3.9.2 Fixes Fedora 19 Issues

First of all, we should mention that version 0.2.7 of the libosinfo library is now required for compiling GNOME Boxes 3.9.2. Second of all, GNOME Boxes 3.9.2 fixes many bugs reported by users from the previous unstable release, such as password/username entries focus issues on each key press, unwanted ‘_’ in the wizard toolbar button labels, as well as a regression that disables GNOME Boxes from connecting to the same box.
