Fix download failure due to absolute URL
Fix download failure due to absolute URL

Before, I dumbly assumed that all media URLs were going to be relative to
http://wol.jw.org.  Now that they fixed the video links to jw.org,
this isn't the case anymore, so my simple string concatenation to
create an absolute link would create invalid links.

I tried to implement video loading, but a chain of redirects fails for
'request' while it works in a browser.  I haven't yet figured out why.
This causes all the video links to go to the jw.org homepage for
my script, and they somehow pick up some world map images.
