[1.11/1.11.2] VSE v7 - Can't touch this.

• Add new climbey options for server owners. You can now either whitelist only certainly blocks for climbing, or blacklist certain blocks from climbing. Should allow you to setup your server how you want for most players while supporting some kind of climb-courses.
• Plugin now outputs a config-instructions.yml which has comments in it. Make sure you actually edit config.yml.
• Don't save config on plugin disable.
