Fixes

 * – Villagers ignore damage values and item tags in trading
 * – Players can place and remove arbitrary blocks in Adventure mode, breaking pre-1.4.2 maps
 * – Random destination routine has a small statistical tendency to move more north west (fix included)
 * – Zombies kill villagers instead of transform them (HARD difficulty)
 * – Chicken Jockeys causing lag on Multiplayer servers

Notable issues

 * Water and Lava no longer flow toward the nearest drop when possible, instead always flowing outward
 * Because of this, these liquids tend to spread out on slopes over a much larger surface area.
