Trapped Chest

Trapped Chests are blocks which emit a redstone signal from all sides when opened, at a strength of one block per player using it. The Trapped Chest can be told apart from a regular chest by a slight orange tint around the latch and a red line on the rim of the opened chest. Trapped Chests can be made into double Trapped Chests, and are able to be placed adjacent to normal chests without interfering, allowing two chests, or double chests, to be placed adjacent to each other.

Bugs
If there is TNT under the chest and it goes off when the GUI is open, then the game crashes.
