New items

New entities

 * Skateboard: A wheeled board that rolls on the ground, the player may right click to ride. If placed on snow, the wheels are removed and a pair of attached boots are added. After two seconds of sliding randomly, the board zooms out from under the player at great speed, and the player falls and takes 1.5 hearts of damage. After the third consecutive face-plant a browser window is opened and redirects to a URL for purchasing a real skating game. If FrankenKraft is also installed, then when the player alt-tabs back from the browser window, his movement is slowed and his Steve is drawn with a cast on one of its legs.
