rc repl x11: allow arg for repl send & refocus kak

tmux-send-text allows sending an argument, when supplied the argument
will be sent to the REPL instead of the current selection.

tmux-send-text also keeps kak focussed, which does not happen in the x11
variant as it uses xdotool to switch window.

this patch allows:

 * Passing an argument to x11-send-text, so that value will be sent
 instead of the current selection.
 * We capture the window id of the current (presumably kak window)
 before we use xdotool to switch window. We can therefore switch back to
 kak afterwards (which we do)
