Changes
Fixes & Changes:
 * New achievements
 * Will limit the amount of Experience Orbs dropped by a player on death.

 * Fences no longer block you from moving onto their space. You can now stand next to them, like you can with glass panes and iron bars.

 * Random loot chests in Strongholds.
 * Blocking will moves the player's arm, rather than the sword just floating right in front of the player.
