ShowItem 1.5.14 - 1.16.2 update and unknown item fix
Added direct 1.16.2 converter and chat replacement adapter (The fallback should've worked already though )
New "Unknown Item" message config (lang.item.unknown) for the chat placeholder to show when the item isn't in the local cache (e.g. when the message ended up on a different server)
Made command name tab completion/suggestion case insensitive
