    messageTray: Add option to (un)mute conversations
    
    Add "Mute"/"Unmute" option to the right click menu for chats to allow muting conversations
    without blocking the sender or disabling all non-urgent notifications. Muting a conversation
    prevents the pop up of notifications on new messages from the muted source, while these
    messages are still available from the summary notification in the message tray.
