Gates

You can now paint blocks individually as requested by InTafiir, not only that you can choose the open and close block so you can have separate animations. I've also added a help command use /gatehelp this comes with a new option as well where you can use json in the help command (requires: json.sk) * New command: /gatehelp Bug Fixes: * Fixed a bug where if you force closed the server while a gate was in it's animation the animation wouldn't ever trigger unless you used a developer command to delete the variable. This bug is very rare but since I constantly force close my development server I came into it a lot during testing so I've fixed it
