[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.

# Idea is to turn off all key bindings and prefix handling on local session,
# so that all keystrokes are passed to inner/remote session
# see: toggle on/off all keybindings · Issue #237 · tmux/tmux - https://github.com/tmux/tmux/issues/237
# Also, change some visual styles when window keys are off
