3D armour that protects, and sets that face the right way

• New: 3D armour can give armour points and wear out. Add armor3d: <set> to an ordinary item with an armor: slot, and it wears that piece of the 3D set while keeping its own name, attributes, durability and recipes. See 3D armour.
• Fixed: a 3D armour set made on Blockbench's player template (or a Bedrock armour template) was worn backwards, with each arm's parts on the other arm and the icons facing away. RP Engine now works out which way a model faces, so either way round is right. Nothing to change in your models.
• New: /rp cast <name> at <x> <y> <z> [world] plays a VFX at a place instead of on a player, from a player, a command block or the console. It has its own permission, rpengine.cast.at.
