Add a scope to expose native GTK apps (without Xmir)

[Daniel van Vugt]

Add a scope to expose native GTK apps (without Xmir).

In future we'll be able to run most GTK apps natively in Mir/Unity8 without using Xmir/X11. Some of them kind of work already:
    gedit -- --desktop_file_hint=unity8
    sol -- --desktop_file_hint=unity8

However we will need a Unity8 scope that exposes the availability of such built-in apps to the user.

Status changed to 'Confirmed' because the bug affects multiple users.

If the .desktop files have the correct attributes, then the apps scope will already show them. However, it's my understanding that we won't generally support all native apps installed to the system, as things that can be run under Mir, as so many just won't work, and even if they will launch because the toolkit has a Mir back-end, the confinement and app lifecycle restrictions would also cause problems.

[Daniel van Vugt (vanvugt)]

I half expected that answer. Just want people to start thinking about it now.

We could curate the list by hand, as apps are found/fixed to be working. Alternatively we could add a switch to eliminate the confinement limitations so people can run arbitrary legacy software (and there will be more demands for that, so be ready for it).

It appears this now exists. Just push the mouse (quickly) against the left edge of the screen to get the full list of apps.
