Vizlib Teamwork Subscription settings (unsubscribe as default)

When a user first leaves a message in the Teamwork chat, he automatically subscribes to notifications. There is also information on how to unsubscribe from notifications, but this is not always convenient, since user has to unsubscribe from all chats where has has ever left comments.

It will be more convenient to have a possibility setting up the "Unsubscribe" feature as default.
