a custom /set [action ][msg] command#722

a way to make a custom /set [action ][msg] command.

reasoning: i don’t use /set leave message but i’d like to send another message after the welcome message was sent. i use a different bot to verify users after mimu sent the welcome message. it would lovely to be able to use the /set command for something else as /set leave msg isn’t being used.

two channels involved.
welcome msg - welcome channel (default behaviour)
custom msg - new channel (potential new behaviour?)

what i want additionally:
create a custom set msg - like an announcement message sent to a specific channel.
