* If that fails, try to load the NIB from the main application bundle,
* which is where most NIB resources are to be found.
* Possibly this is the wrong order ... since it's conceivable that an
* application may supply an alternative NIB which it would like to have
* used in preference to the one in the classes bundle. However I could
* not find the behavior documented anywhere and the current order is
* most consistent with the the way the code behaved before I changed it.
