Carpet LAB Addition

Carpet features created for the LAB SMP, as we need them.

Carpet rules

noteBlocksBroadcastSigns

• Makes note blocks with signs standing on top send the sign's text in chat when triggered.
• Requires the first line on the front of the sign to be a broadcast marker: [BROADCAST]
• The broadcast marker can optionally supply a radius between 1 & 48: [BROADCAST 16]
• Default broadcast radius is 24.

shulkerBoxesDoNotBreakPaintings

• Makes shulker boxes not break paintings or item frames when opening into them.

Scarpet events

__on_player_message_broadcast(player, message)

• Triggers right before a player message is broadcast to the server.
• Can be cancelled by returning 'cancel', which prevents the message from being sent.
• Useful for making changes to chats before they're sent.

__on_player_edits_sign(player, block)

• Fires after a player edits a sign, after the vanilla text changes take place.
• Can be used to add custom sign formatting.
• Example script

Scarpet functions

encode_snbt(expr, force?)

• Essentially the same as encode_nbt(expr, force?), except it allows heterogeneous lists
• This is done to bring it in line with vanilla's new NBT format
