r516 - 1.4 plus Ropes & Chains

Decided to release a 1.4 version after testing with the Mayan Temple at least being successful.  Tomorrow will look at releasing another version with looking at lighting plus some other stuff.

• Upgrades to 1.4.
• Adds ropes and chains which can be climbed with spacebar if they are vertical and can walk on horizontal ropes/chains.
• Wolves can also be spawned from the mob spawners.
