Additions:

• added the /nextspawn command, which skips the time remaining to spawn the next wave of mobs
• loose stones can be thrown; they deal two points of damage
• item dropping has been remade using projectiles to make the animation smoother
• unused textures are unloaded in order to save memory
• fire blocks set mobs on fire, similarly to how lava does

Changes:

• the player spawns earlier in the noon, to have more time before the night arrives
• beds are now slower at skipping nights, and wolves are likely to spawn if thou sleepest in a poorly lit area
• the player has a grace timer that prevents anything from dealing damage to him for 1 second after respawning
• mobs have a cooldown before they can be attacked again
• forbade placing blocks where entities stand (I suppose it should work, but not flawlessly)
• prohibited spawning mobs less than two blocks away from the player
• items are now able to be used on unhoverable blocks, like air
• fixed ore underlayer not being rendered in the player's hand and in FallingSand
• fixed surface copper and brown coal ores not being minable by hand
