Improve:

2. Async send the messages to improve the performance.
3. Async process the some part tasks in displayCheck.
4. Async process the player move event.
5. Mark "ignoreCancelled" for some event on @EventHandler to make bukkit won't send us cancelled event to us to improve a little the performance.
Add:
1. Now InventoryMoveEvent can update the shop sign. (e.g Hopper), you can disable it in config if you feel it cause performance issue.
2. New command /qs supercreate can allow you bypass all protection checks to create the shop, this is helpful for some plugin wrong process the checks event to do wrong actions.
