Import/disable/overwrite commands

[Volte6]

Goal

• allow native commands to be disabled via a config file
• allow commands to be defined in script files (currently only native code)
• scripted commands will be enabled via config file

Rough plans

Scripted command entries will be defined as key/value pairs where:

• key = command (alphanumeric)
• value = path to script
  • path to script file.
  • consider using path "disabled" or otherwise to disabled native commands
  • consider allowing overwriting native commands in this manner.

Script exports

• OnCommand(rest, actor)
• AdminOnly (bool) - is this an admin/mod only command?
• WhenDowned (bool) - can this be invoked when downed?
• AllowUser (bool) - available to users?
• AllowMob (bool) - available to mobs?
• Requires ([]string) - a list of dependency commands required for this command to work.
