[Crash] Provide custom toolbar view.

[ypopovych]

I need another type of toolbar (for speech recognition, so no textView in it).

I subclassed JSQMessagesToolbarContentView and JSQMessagesInputToolbar. In JSQMessagesInputToolbar I implemented loadToolbarContentView and returns my initialized toolbar. But JSQMessagesViewController try to create JSQMessagesKeyboardController for it, and crashes on textView != nil assertion. How I can disable creating of keyboard controller?

@ypopovych can you please provide some more detail about how you replaced the stock input toolbar with your custom subclass? I can't figure out how to connect subclasses of those with JSQMessagesViewController, as the inputToolbar property, and its contentView are both read only. I've tried fiddling around with overriding the property and only achieved KVO-related crashes for my pains.
