Item Frame

The item frame is an upcoming item similar to a display case. It will show the item or block that is in it. The item displayed can be rotated by right-clicking the frame. Maps will show their contents and compasses and clocks will work as normal. Frames can also be placed on cactus blocks, fences, and slabs where they act like a sign. The player can walk through them undisturbed. Unlike with paintings, it is possible to place an item frame on each wall in a one block space. When broken (easily possible by hand) the frame drops both itself and the item it contains.

Bugs

 * Right clicking with more than one of a stackable item will put all of the stack into the frame, however, you will only receive one of the item you put into it.
 * Pick-Block-Key gives the item in the frame, as opposed to the the frame itself. (May be intentional.)
 * Torches can be placed on item frames, but only indirectly.
 * Major: Attempting to place an item frame in multiplayer will disconnect the user with the message; internal server error.
 * Attempting to place items in Item Frames such as water/lava buckets, splash potions, fishing rods, and others with a right-click function will cause them to be used,
 * In the case of fishing rods, the fishing hook can take the frame off the wall.

Trivia

 * The item frame is based off a suggestion on Reddit, like the Ender chest and flower pot.
 * A map put into an item frame will show markers at any other item frames with maps in them. This is a good way to mark certain areas.
 * Items appear flat in the frame while blocks protrude from it.
 * Due to it being a separate crafting recipe, framing colored wool is currently impossible, as it will create paintings instead.
