Explicitly send X-Plex-Token as URL parameter (Kodi 17.0b6-Krypton)

[gritstub]

As of Kodi 17.0b6-Krypton [1], curl will no longer send all headers blindly.

This results in (at least) thumbnails not loading, and errors:

This patch adds the token as a URL Parameter [2] of the URL returned from get_kodi_header_formatted_url

Not sure if this is the correct branch to base this pull request on.

I can confirm the issue, but I'm pretty sure that isengard-helper-merge is not the right merge target. I think it should be helix.

Then again I am not sure if there is still anything happening at all in this project. :(
