This fixes #49.
Introduce a common architecture between interactive mode and cli-studio namely TastyCommander.
Preps also for #33

@hazard999 the main problem when thinking about the cli-studio is if we keep using Terminal.Gui we are totally out of control. If we use system-terminal we loose built in controls and mouse support. On the long run I guess going with a own gui would be better cause we have more control.
It also is a little bit more fresh and doesn't use ncurses, so less dependencies to worry about.

#46 and cli studio need the same sort of abstraction

basically we need something like XtermSharp but over the wire
