Update example that uses proxy to trace all events to use ListenerProxyElement.

Update terminology in readme file.

PARB feedback: Rename playhead to currentTime, bytesDownloaded to bytesLoaded. Affects traits, MediaPlayer, and events. Updated dependent unit tests and sample apps.

This is an empty revision for padding.

PARB feedback: Refactor MediaPlayerState to convert constants to strings. Remove all other methods. Update dependent code.

PARB feedback: Refactor StreamType to convert constants to strings. Remove all other methods. Update dependent code.

PARB feedback: Refactor ScaleMode to convert constants to strings. Move utility function into dedicated utility class (ScaleModeUtils). Remove all other methods. Update dependent code.

PARB feedback: Refactor our DynamicStreamingResource class (and hierarchy). Introduce StreamingURLResource and StreamType to lay groundwork for live support. Fix some bugs related to seek not working when a duration is unspecified (NaN). Further refactor unit tests to make them toggleable between hitting the network and using mock objects (still a few tests that fail against the network).

rollback the changes made to hide so called DRM content here, as Brian pointed out that "the ContentProtectableTrait stuff isn’t 10.1 specific, it’s generic infrastructure for which the 10.1 DRM is one possible implementation. (In theory, someone could create an implementation that uses a web service for authentication.) The less stuff we have to make 10.1 specific, the easier to manage."
