Use `-q` when using the tmux client `set` command.

Mute tmux command output on a command level and not globally. This
ensures that if another client disables the quiet option, Guard
commands to tmux still don't show up in the console.
Tmux notifier can be configured to set the title.

The tmux title notification shows the title and the first line of the
message in the terminal title, allowing to configure different formats
on success, pending or failure like for the display message.
