Disable notifications when present

[avidseeker]

Expected Behavior

When actively participating in a chat, don't send notification about new messages from that chat.

Current Behavior

All notifications from currently active chat are shown.

Possible Solution

Profanity has a presence detection that automatically sets "AFK" when no interaction is happening. When a chat window is open and user presence is detected, don't send notifications about the opened chat. Presence should not be detected when profanity is in a detached tmux session.
