- fixed the Tcl Command Help to work as expected; made the text of the commands to be colored in Red color and bold

- added a 'Close' menu entry in the Tcl Shell context menu that will close (hide) the Tcl Shell Dock widget
- on launching the Tcl Shell the Edit line will take focus immediately
- in App.on_mouse_move_over_plot() method no longer will be done a setFocus() on every move, only when it is needed
