Correctly parse the player URL in RTMP downloads (closes #11)

Fixed several problems courtesy of jamiejones:

The parsing for the SWF url was wrong (the "//" are now escaped and the
initial .*match needs to be 'ungreedy'), so the -W setting to rtmpdump
was not set, causing the decryption of the video to be wrong.

Finally, add "&has_verified=1" to the fetch of the HMTL page to
allow fetching of age-restricted videos.
