Improvement: add commands to actions

[TomLewis]

Ahoy

Please can you add a way to run commands as actions with placeholders for the action name and entities.

Then we can use it for things like testing actions to get feedback and logs.

For example I want to make a discord channel to log each time this changes, and if possible why, for example the entities that caused the action to happen.

So then we can be proactive with logging and look into where these are to see if it's a player or server issue that can be resolved.
