[ ] Show 'Bust' when player busts in pig (requires fix to #396 so busted can be observed, unless we cheat with something like Computed.Global.BustCount or state.player.0.BustCount)
[x] Show 'Bust'/ 'Stand' in Blackjack
[x] 'Match' when two matching memory cards are shown
[x] 'Your turn' when current player is switched to be you (BaseGameRenderer should get an isCurrentPlayer computed property (pig has an impl). But that requires all subclasses to extend properties() object
[x] Some way to trigger only when it switches to true
Should there be a that takes the value and renders the text but also automatically does the animation?
Or perhaps it's just a different configuration on boardgame-fading-text
