• Squashes the region lead role command into a toggle
• Renames commands to be more intuitive. We now have /lead region role and /lead vc rename for example
• Small eslint changes that came up while working on this
• Remove some redundant permission checks
• Bugfix for region role command, in which all of your regions had to match the target. Now only one of the roles have to match the target, which makes more intuitive sense.
• Minor language tweaks
