Added code to the GTK+ Area to print the GdkKeymapKeys for a given key value. For GTK+/X11 it appears that we can just use the keyval field... that just leaves GTK+/Wayland (see previous commit). If the same applies, we'll need to see if I can feed artificial keycodes in and it'll still work as expected...
