Make "Quit" button work on "q" or "Escape" key press

Previously I only had a key equivalent on the "Escape" key because you
can only set a single key equivalent. But I wanted the "Quit" button to
work on both "Escape" and "q" presses.

I tried to do this by overriding `performKeyEquivalent:`:

    - (BOOL)performKeyEquivalent:(NSEvent *)theEvent
    {
        if ([[theEvent characters] isEqualToString:@"q"] ||
            [theEvent keyCode] == kVK_Escape) {
        NSLog(@"%@", theEvent);
            return YES;
        }

        return [super performKeyEquivalent:theEvent];
    }

The method was called and it logged correctly, but the `IBAction`
wouldn't run. Maybe this doesn't work for what I want it to? Can't
figure out what the problem is.

Didn't want to deal any more so just overrode `keyDown:` instead and got
rid of the `IBAction`, just terminating the application in code.
