Merge lp:~donadigo/appcenter/apt-link-support into lp:~elementary-apps/appcenter/appcenter

[Adam Bieńkowski]

* Add support for appstream links

This branch fixes bug #1628476: "Affiliate AppCenter with x-scheme-handler/apt mime type".

Most of the scheme handling code was taken from the recent switchboard change at revision 691.

This branch actually implements handling for appstream links as discussed on Slack instead of apt links.

To test run e.g:
appcenter appstream://org.pantheon.snap.desktop

Instead of apt, support appstream

[Corentin Noël (tintou)]

Tested with xdg-open appstream://org.pantheon.appcenter.desktop
Working as expected
