This file works on Minecraft 1.11. It also works on Minecraft 1.9 and 1.10 if you have an existing config file, or if you remove the shulker boxes from a newly created config file.
Added shulker boxes to the default list of protected containers. If you have an existing configuration file, you'll need to add those blocks manually.
You can now place protection signs to the left or the right of a door.
Trapdoors can now be opened and closed automatically, just like doors.
Added sounds to auto-closing (trap)doors
Fixed [Timer: X] (with a space between : and X) not working.
Made some block checks done by the plugin a bit faster.
