V1.2.1

Changelog:

• Giving the map/schematic name in mp list command as an argument will now show detailed description of that map/schematic
• Highly optimised schematic spawning method
• Added schematic_block_spawn_delay property (default: 0, equals to one frame). It is a delay between spawning each blocks of a custom schematic. Higher values will make "spawning process" take longer, but they may prevent lag/client crashes for very big schematics.
  Set it to -1 to disable the delay entirely, but it's not recommended
