Small update: maps and water — Chessboard Kingdoms Steam update #1416241

In this latest updated we included two new maps, Plaza and Cliffside Cross. Plaza offers a new layout idea, with flag drop areas being available behind enemy lines, forcing the player to play aggressively. All that only concerns the Flag game modes. Otherwise the map can be played as usual. Cliffside Cross is just a medium-sized map for up to 4 players and some cool terrain. We also upgraded our water with refraction, better normals, and underwater fog color. Perhaps a few tweaks will be needed, but it is a major step up from how it looked before.
