Set the accelerator path on this, through which runtime changes of the menu item’s accelerator caused by the user can be identified and saved to persistent storage (see save on this).
To set up a default accelerator for this menu item, call add_entry with
the same accel_path. See also add_entry on the specifics of
accelerator paths, and set_accel_path for a more convenient variant of this
function.
This function is basically a convenience wrapper that handles calling set_accel_path with the appropriate accelerator group for the menu item.
Note that you do need to set an accelerator on the parent menu with set_accel_group for this to work.
Note that accel_path string will be stored in a Quark. Therefore, if you pass a static string,
you can save some memory by interning it first with g_intern_static_string.
