Fixed default schematic compatibility with 1.20 (Delete schematics folder to get new correct)
Fixed possible sign replace issue (When sign is replaced with LuckyBlock). This feature is available for 1.13+
Added new schematic param ( air ). If you add one more "true" argument to SCHEMATIC drop or add json field air with value of true, the schematic will be pasted as command (//paste -a, ignoring air)
