appstream:/id URL handler

[aleixpol]

It would be really useful to have such a URL handler so that if the user clicks a URL with "appstream:" scheme, he launches Discover/Gnome-Software/Whatever.

This could help a lot minimize the access barrier to the projects we offer since we'd be leveraging a cross-distro naming scheme, therefore not compromising when giving a package name (like it used to be done with apt:/).

This simple patch does the trick in Discover.

Will be in the next release, as discussed on IRC :-)
Thanks for reporting this!

KDE Discover and GNOME-Software support this feature now :-)
