Installs an accelerator in this group, using an accelerator path
to look up the appropriate key and modifiers (see
AccelMap.addEntry). When accel_group is being activated
in response to a call to gtk_accel_groups_activate(), closure will
be invoked if the accel_key and accel_mods from
gtk_accel_groups_activate() match the key and modifiers for the path.
Note that accel_path string will be stored in a GQuark Therefore,
if you pass a static string, you can save some memory by interning it
first with g_intern_static_string().
