Title: Fixed inability to create IBAction methods in preference NSViewControllers

The problem was mainly in the line

NSViewController *result = [NSViewController alloc] initWithNibName:nibName bundle:nil];

I changed it to

NSViewController *result = [[NSClassFromString(controllerName) alloc] initWithNibName:nibName bundle:nil];

However, as a result, `existingViewControllerForToolbarItem` no longer worked properly; `nibName` was sometimes nil. I converted `self.viewControllers` into an `NSMutableDictionary` mapping from controller names to `NSViewController` subclass instances and stopped referring to the view controllers by the `nibName`. I also took the opportunity to rename the xib files without the `'Controller'` suffix, as is recommended by Apple's docs.
