Kill application.py, port to GTK Application
Submitted by Jeff F.T.

I've been pondering for a while killing Pitivi's menu bar and using Gtk's appmenu. This would allow better integrating with GNOME Shell and other platforms, eliminate redundancy and save screen space (because the application could now be undecorated when maximized, as first suggested in bug #T2954).
Most of our menu items are either duplicates of what we have in toolbars, or could be moved to a GtkApplication menu.
Some items would probably need to be moved elsewhere in the UI:
“Revert to saved” could become a full-fledged main toolbar button.
"Export as archive" → “Gear” menu
Detach/Attach viewer → Make it a button in the viewer’s toolbar
Save snapshot of the current image → “Gear” menu
Keyframe actions: they should be contextual anyway. Either in the effect properties UI, or appearing temporarily in the timeline toolbar (to avoid visual clutter). Will depend on someone actually implementing the keyframe UI.
"Remove layer": kill the menu item, leave the contextual menu, and replace the main interaction by “drag the layer out of the screen or into the media library”? That one is going to depend on our port to a clutter timeline/some other expert than me.
I'm left wondering about the relevance of a "gear" menu (à la Chromium/Epiphany/Nautilus), given that GTK's toolbars will automatically create a "dropdown" arrow if it can't fit all items on the screen...
