OCGV: Add ability to minimize UI

The window border, filter box, and status bar use valuable screen real estate. I’d like to have an option of not having it visible.

I considered having parameters for all of them:

• -NoFrame
• -NoFilter
• -NoStatusBar

But that seems overkill. Instead, just:

• -MinUI

I just pushed a change to Terminal.Gui that will enable hiding the statusbar. Then all that’s needed is to change the logic that creates the Window to:

        private Window AddTopLevelWindow()
        {
            // Creates the top-level window to show
            var win = new Window(_applicationData.Title)
            {
                X = _applicationData.MinUi ? -1 : 0,
                Y = _applicationData.MinUi ? -1 : 0,
                // By using Dim.Fill(), it will automatically resize without manual intervention
                Width = Dim.Fill(_applicationData.MinUi ? -1 : 0),
                Height = Dim.Fill(_applicationData.MinUi ? -1 : 1)
            };

            Application.Top.Add(win);
            return win;
        }

Actually, I would love the -NoFrame, -NoFilter, and -NoStatusBar that were proposed. I very frequently desire some of those but not others.

I’m not married to the name HideUIElement but I do think this kind of parameter seems pretty cool. I like adding All and None where None is the default value.
