Smooth World Loading Screen

First release.

The loading screen shows the last thing you saw in that world or server instead of plain dirt: leave a world at your base, come back to your base. The view is taken quietly as you play (no hotbar, no hand), and on pause.

• One picture per world and per server.
• The progress bar stays; the chunk map square is hidden over the picture.

Client-side only. Works on any server.
