MacGui: Loose Anamorphic initial implementation
- Changes the PAR checkbox to an anamorphic NSPopUp Button with "None", "Strict", and "Loose".
- Sanity checks against the ffmpeg encoder, until that gets fixed.
- removed six unneeded outlets for picture sizing in Controller.mm.
- Previous presets will gracefully degrade to us "Strict" if anamorphic is specified.
- I know about the bug where the picture window changes size on the first width drop when resizing Loose Anamorphic, so dont ask ;)
