Stop working after registering the same input after cancellation about masshortcut

[hatashiro]

Just found a workaround like below, but not quite sure if it's rightly done.

// swift
func shortcutValueDidChanged(sender: MASShortcutView!) {
    if sender.shortcutValue == nil {
        resetShortcutBinder()
    }
}

func resetShortcutBinder() {
    MASShortcutBinder.sharedBinder().breakBindingWithDefaultsKey(shortcutKey!)
    MASShortcutBinder.sharedBinder().bindShortcutWithDefaultsKey(shortcutKey!, toAction: selectInput)
}

@zoul Hey Tom, I'm calling for help 😆 Maybe some cleanup needed?

I’m currently offline, will take a look at the issue on Sunday or next week. Since the bug is reproducible, it should be easy to fix.

I think this #71
