Frank LENORMAND 678acd32bc Introduce rc/tmux.kak
This commit adds a kak script dedicated to tmux support, and declares
new command to interact with the current tmux session. Users are now
able to create vertical panes or horizontal panes arbitrarily (as
opposed to setting the `termcmd` variable to the proper command). The
script also has its own `focus` function, used to jump from a  pane to
another.
