Support Plex authentication.

This has been working great for me until yesterday when I setup users and now each user requires a pin. Is there anyway to work around this ?

I've been looking to figure this out with my own plex scrobbler but going through the Plex api I haven't been able to find an easy way to get PMS user data.

The server logs will occasionally log user names and their ids so it is possible that you could periodically scan the logs to get this data and then associate it with whichever last.fm profiles have been authorized - but it seems a little bit hacky.
