Bug#1114463: ITP: bazaar -- New FlatPak App Store for GNOME

[asciiwolf]

Thanks a lot for working on this! This will be a significant help for
Flatpak users on Ubuntu and various lightweight Debian systems. The deb 
version also supports Flatpak installation from user remotes, unlike the 
official Flatpak version that will likely never support this because of 
Flatpak limitations.
