[tmux] Add remote session nesting

Browse source 
If calling a tmux session within a tmux session, pressing F12 will
toggle between sending commands to the outer or inner session. If the
outer session is inactive its status-bar will be slightly greyed out to
show that no commands will reach it. If the inner session is a remote
ssh session, it will set some additional stylings for the status-bar to
further differentiate the two.
