[FEATURE] Warns, mutes, etc should allow to include a message for context

[elkowar]

Is your feature request related to a problem? Please describe.

sending out warns for specific messages tends to be somewhat anoying, as concrete context is often missing.

Proposed feature

when including message links in warns, mutes, etc, the respective message should be fetched and included in the database entry, and somehow included in the !notes output.

One way to implement this could be to copy over the linked message into a #context channel or just modlog automatically (in an embed) and then including a link to that message in the notes entry.
