Minecart with TNT

A minecart with TNT (can be called a TNT Minecart) is a planned vehicle to be added in the Redstone Update. The TNT is activated by hitting the Activator Rail. The TNT explodes immediately after it's derailed.

Crafting
A Minecart with TNT is crafted from a TNT and a Minecart, as shown below:

Bugs

 * Tnt-Minecarts not only get activated by Activator Rails, but Powered rails too.
 * 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 an explosion or a crash. []
