Output HRESULT as hex on Metro activation failure

This confirms that the error for issue 327101 is E_APPLICATION_NOT_REGISTERED (0x80270254); this makes sense since in browser_tests, it's the test runner, not chrome.exe, that is registered as the "default browser".

Flag for disabling P2P STUN filter

Temporary flag for disabling P2P STUN validation on UDP sockets to let the cast team use it
until the final design is implemented. The final design will send encoded frames to the
browser process, which will split them into packets and handle the encryption, thus making it
very difficult for the renderer to talk other protocols.
