Fixed bug 4747 - [Patch] SDL_ShowMessageBox ignores BUTTON_RETURNKEY_DEFAULT flag 

Caleb Cornett

SDL_ShowMessageBox on UIKit doesn't do anything special with buttons that are marked with the flag SDL_MESSAGEBOX_BUTTON_RETURNKEY_DEFAULT. According to Apple's documentation on UIAlertController, a button can respond to a return key if it's marked as the preferredAction of the controller. SDL doesn't set a preferredAction currently, so I've attached a patch to fix that.
