Added AVAsset and AVMetadataItem

- Modified NSSoundExample with new classes.
- Added CMTime and related constants and functions to Cocoa module.

- Fixed NSSoundExample to handle .m4a files.
Made additions to classes

- Added properties/methods to AVAsset, AVAssetTrack, AVMetadataItem.
- Replace For Each in Cocoa.NSObjectFromNSPtr since order matters.
Added AVMetatadataItem.PictureValue

- Yeah, a convenience method, but one that will be needed a lot and
consistent with other, native properties.
- Renamed NSSoundExample window and menu item to reflect the additional
classes it illustrates.
