Installs the accelerator for action if action has an
accel path and group. See gtk_action_set_accel_path() and
gtk_action_set_accel_group()
Since multiple proxies may independently trigger the installation
of the accelerator, the action counts the number of times this
function has been called and doesn't remove the accelerator until
gtk_action_disconnect_accelerator() has been called as many times.
Since 2.4
