Changes

* When using a mode other than the default one, the mode setter (red) has to announce it in the lobby before the game starts. Every player must be informed, so they have the opportunity to leave in case of dislike.

** Mode for 3.5 Beta is: -sdgmcb

* Refusing/Avoiding to heal.

* Refusing to cooperate when asked to do so several times by sending alone and not save-send with teammates to win.
