Metadata refactoring revision: having LayoutMetadata return a NullMetadataSynthesizer so that child layout settings do not get copied to their parent.

Fix bug in ProxyElement's blockedTraits implementation. Blocked traits take precedence over overridden traits. The bug was that events would still be dispatched for an overridden trait being added even when the trait was blocked. Update unit tests.

Fix bug FM-282: MockNetStream doesn't signal onMetadata for negative durations.

Fix bug FM-329 - seeking in DurationElement resets currentTime to zero. This revision fixes a number of playback/seek/completion issues in DurationElement, including loop and autoRewind behavior.

Fixing TestDVRCastNetStream to work correctly from AIR.

Fix compile error when logging enabled.

https://bugs.adobe.com/jira/browse/FM-238. Complete fired at random times near end of video. Duration fix ups to not collide with the audio delay fixes to garuantee seek(0) works.

Commit example showing how to perform additional load logic via a ProxyElement. The AsynchLoadingProxyElement (and its corresponding LoadTrait) load the proxied element, but doesn't expose its READY state to the outside world until it performs its own load operation (in this case it just runs a Timer). Include minor fix to other example.

Commit some proxy fixes related to the use of blocked traits. Update unit tests.

Updated ASDocs to relfect the fact that the duration element doesn't work with media elements that already have a time trait.
