Player Roles

• Ensure all roles are assigned unique levels instead of silently "masking" other roles with the same level
• Send feedback to the player when they are muted and support muting through /msg and /teammsg command
• Allow for roles to inherit overrides from other roles (#22)

"foo": {
  "includes": ["bar"]
},
"bar": {}

• Support applying roles to command blocks and functions

"foo": {
  "apply": {
    "command_block": true,
    "function": true
  }
}

• Report parsing errors to the player when running /role reload
