Moved the DivePlanner to the MainWindow.

Now, activating the dive planner will hide the profile
and show the planner on the same place. we still need

Added the Ok / Cancel buttons on the dive planner canvas.

Added the ok / cancel buttons on the dive planner canvas.
I still need to hook the esc button to cancel it too, but
