Original issue's description:
> Include the AppData file for Chrome and Chromium
> Add the two AppData files, one for Chromium and one for Chrome. The Chrome one
> will be filled with the information from the common/google-chrome/
> file and should reflect the current channel (stable, beta, devel). On the other
> side the Chromium one should be a general one and it will be reused by
> distributions that are packaging the Chromium themselves.
> For AppData specification please see:
