Lamp 0.21.0

• Attach files when you wish for something new: press + in the desk's bar or drop files on it.
• A game is one of its wish's apps everywhere it's played, on your Mac, iPhone, iPad, Android phone or Xbox: it sends
  messages, values and files to the wish's other apps, like any of them. So is a screen.
• A new game shows the same card a new app does while Lamp makes it, instead of a ball on a floor.
• A new wish's first message no longer shows twice in its chat.
• The chat beside an app is named after the app, and a turn's cost says when it was spent on pictures.
