Use new GLib application API for launching

Browse Source 
Launch child processes more directly; we retrieve the PID, and
use it to keep track of the .desktop file we launched.

Now, when we get a window, since the X window has a PID, we
have a pretty strong association.

.desktop file <-> PID <-> window

And can thus map window back to .desktop file.
