Quality Commands

Added new block. This block (obtainable via using \give @s quality_commands:barier) will only have a block outline while you are holding it (similar to minecraft:light). However, it always has a physical hitbox, and is therefore usable for map boundaries. Where you don't want them to go, they will not go.

Update to \tpRel! New optional argument: rot Old uses still work.

New Usage: \tpRel target from to [rot] If rot is present, rotates the target position around to. For when you want the turning to be smooth. Also rotates velocity for smoother transitioning. If rot is not present, acts as before change.
