add main components for tcl frontend

   The tcl version now accepts button presses and key presses. It has
   the buttons in the same layout as the gtk frontend.
   Also had to modify the action functions, to accept an additional
   useless parameter because of how tkinter was calling the functions.
   Still need to add icons.
