Handling of vanished players

[GeorgH93]

Description:

Messages like "Your partner is online" should be hidden if the partner is in vanished mode.

At the same time it would be nice to allow your partner to see you while you are vanished (if you have given consent).

Implementation:

• [ ] Vanish check for status messages
• [ ] Command for players to allow their partner to see them when they are vanished
• [ ] Make vanished partners visible when they have given their consent

To add to this the /listpriests command should also exclude vanished players.

To add to this the /listpriests command should also exclude vanished players.

This should be fixed with this build.
