Support Minecraft "local" coordinates

In 1.13, Minecraft has added Local coordinates, which is a third coordinate system (in addition to relative and absolute coordinates). It uses caret (^) notation, is centered on the player’s head, and rotates with the head! Here is the wiki’s 1-line explanation:

For caret notation, they are along axes originating in the center of the target’s head and pointing leftwards, upwards, and forwards, respectively, changing with the head’s rotation.

A few examples:

• ^0 ^0 ^0 is the player’s head
• ^3 ^0 ^0 means 3 blocks to the left of the player’s left “ear”
• ^0 ^0 ^5 means 5 blocks “forward” in the direction the player is currently looking

In my opinion, the best use of this is to change the default position to a block that says “In front of me” and have that map to something like ^0 ^0 ^5. That way, beginners don’t have to learn relative and absolute coordinates to start placing stuff in an intuitive way. They could do things like “Place [dirt] [in front of me]” and that would make the block appear in a visible location no matter their position and orientation. Major win!
