Additions:

• leaves sometimes emit particles
• added tarsenack, a dark block that forms its own layer below the stone layer. In that layer ores take the tarsenack background instead of a stone one. Currently unbreakable.

Changes:

• the reach range now applies when attacking entities
• the player now starts the game earlier, with more time to prepare before the sun sets
• wolves have been made tougher
• lit torches drop unlit torches
• maximum health range is shown, and the heart texture has been updated
• fix empty stacks being skipped when searching for empty stacks
• the mob spawning mechanism now also takes the light level into consideration
• buffed some ores
