Fix Audio and Video elements.

This patch contains several fixes:
1) Partial support was broken (always returned not supported) for Audio and Video. This has been fixed.
2) Public constructors for Audio and Video elements have been removed.
3) Resources have been re-encoded to be much smaller, and have been moved to public-test.
