A battle's link now comes with a picture

Every battle page has a picture: add .png to the battle's link. It is the page in one image, with the player's name on the left and the opponent's on the right, both decks as the game lays them out with each card's level, average elixir and elixir leaked, the towers' hitpoints, how it ended, and the link. A battle's link shows it when you paste the link into a chat, and the page's Share image and Copy for a post buttons give you the picture and the link to post. Contract 9.18.1.
