PARB changes: Remove metadata from MediaContainer and LayoutTargetSprite constructors. Instead, metadata is set on LayoutTargetSprite via a non-public setter used by the framework. Update a bunch of ASDocs, make some enum classes final, remove elementIDs from sample apps (since they rely on metadata, and we want to keep samples focused on the public API).

Updated DRMState constant names

Modify the MASTSample project to use the new constants for the metadata namespace in the MASTPluginInfo class.

Modify MAST plugin integration test to use the new metadata constants in the MASTPluginInfo class.

Updated Project files.

Step 3. Removed Listener Proxy Element.

DVR: committing unit test progress, minor implementation updates.

Step 2 in removing ListenerProxyElement. Remove units tests, plugin dependencies, and sample app usage.

Moved constants for namespace (also added a version number to the namespace) and the metadata key to the MASTPluginInfo class so these constants can be used from player code.

PARB changes: Update ILayoutTarget ASDocs to remove references to LayoutRenderer.
