MacGui: Separate Picture Settings and Preview Window Initial Implementation

- Picture Settings is now a hud style inspector panel:
-- Allows more room to be displayed along with Main Window.
-- Has button (though ugly ... for now) to open the preview window.
- Separate Preview Window:
-- Preview Window can now show the entire preview content via a hud style overlay controller (ala iTunes, DvdPlayer controls) activated by mouse movement.
-- Has button to allow opening the Picture Settings inspector.
-- Full Screen Mode (ala iTunes, DvdPlayer) which should help for max preview size for HD sources.
- Note: all hud style controls in this implementation are created only using core animation filters, I decided against a third party hud control framework, though one can certainly be implemented at any time.
- Known Issues:
-- WARNING: Quitting HB while in full screen mode will crash the macgui.
-- The hud overlay controls in the Preview Window will align kind of wonky when the resolution is scaled way below the source.
-- Ideally, after moving the mouse within the preview area then stopping, after a certain amount of time the hud overlay control box should disappear.
-- Hud style controls still need alot of development to fit within the HIG.
-- Need a keboard shortcut for the Preview Window.
-- As usual with initial implementations there are likely many more Bugs/Issues.
