Submit a re-sign command that allows users to be resigned to a team

[oddballmeasure]

Since we now offer the feature to convert players to Fa in the discord, this command will printo ut the message if the player is still on the team, and if not, just add the roles if it needs to like the sign command does.

Note that this requires changes to the way the transaction sheets work for resigns.
