keyboard shortcut to toggle results pane
90% of the time I don't need the results pane (bottom pane). When I'm editing queries I want the full height of the editor pane. Therefore add a keyboard shortcut that allows me to toggle the visibility of the results pane. When the visibility of the pane is restored the size is remembered. In that vein, allow toggling of the editor window as well when so I can look at more output. Have an option such that when I execute a query the results pane is made visible (default for this option is true).
