[Feature Request] Custom commands triggered on role change.

[jbagwell27]

In addition to running commands manually through /mc, have the option to have it automatically run a certain command based on rule change. "role added and role removed" With the new features already complete:
player variables in commands
auto whitelist based on roles

Would it be difficult to include a custom command to be run when a player role is changed?
Something like this would be in the config:

[triggerCommands]
[[triggerCommands.rolechange]]
   enabled = true
   added = true #or false
   #or removed = true/false (some way to determine if the role was added or removed in the command)
   discordRole = "patreoncopper" #this would be the role that triggers the command
   mcCommand = "/ftbranks add %linkedPlayer% %discordRole%" 
# or something more specific
[[triggerCommands.roleadded]]
[[triggerCommands.roleremoved]]

It would only work if the player is already whitelisted and linked which would be automated with the aforementioned features. Plus the linked player variables were added too.
