ShellAppMonitor now always assocates windows with desktop files

Track all windows; at the time of opening (and shell startup)
we call into ShellAppSystem to take the WM_CLASS property and
try to find an associated .desktop file.

Add mozilla-firefox to the list of our WM_CLASS workarounds.

Add shell_global_get_screen, since it's often used.
