Meeting notes lacks management

[ZuliusRoolf]

Right now we get discussions in the lab on improvements or ideas for events. Typically they get finalized on the meetings, but the meetings are not often held so discussion topics have a risk to be forgotten.

The discord bot could help with this by the two commands:

• /nextmeeting topic: str reference: link = self.message.id
• /meeting title: str = None

Nextmeeting command will create a note that will be brought up when starting a new meeting.
