Minecart with TNT

A Minecart with TNT is a planned vehicle to be added in the Redstone Update. Currently, it functions as a movable TNT block; with the use of a minecart. The TNT can be activated in a multitude of ways, including hitting an Activator Rail.

Usage
The Minecart with TNT entity acts as a movable TNT block, with the help of an empty minecart. The TNT block can be only activated using Activator Rails from snapshot 13w03a.

The speed of the Minecart with TNT does not affect explosions of Minecart with TNT

Bugs

 * If pushed by the player, they will explode 4 seconds later (Without any TNT animation), however with the explosion animation.
 * If you force two carts together (so that they occupy the same space) and then force them both to explode, you'll get a long period of lag followed by either a Nuke like explosion or a crash on a slow computer. (Dinnerbone nicknamed this "Nuclear minecarts" )
