Improve assassination prompt when aiming to shoot Lovers vs Merlin

[bocaben]

give some sort of indication that the assassin is aiming for lovers as opposed to merlin when 2 players have been highlighted.

we just had a game where assassin accidentally highlighted 1, then when the time to shoot merlin came, he highlighted merlin for the shot but since there were now 2 players chosen, he accidentally shot for lovers instead of merlin, the prompt should clearly differentiate between the 2. perhaps have 2 separate buttons "Shoot Merlin" and "Shoot Isolde/Tristan", where each is one Enabled when the correct amount of ppl are highlighted for that particular shot.

Should be a simple client side addition :).
