Freetube [BAD_HTTP_STATUS: 403] Potential causes: IP block or streaming URL deciphering failed is fixed

If you use Freetube, you haven't failed to notice that Google is on the war path again and broke it a few days ago. See this bug report.

Please note that it's been fixed in this PR. If you download the nightly build #5652, it now works like a champ.

Thanks team Freetube!
