Support for version 1 of plex tv api

[ADRFranklin]

Version 2 of the plex tv api does not contain all the information that the version 1 does. For example /api/v2/friends endpoint seems to always have sharedServers array as empty, while the version 1 endpoint /api/users does maintain which servers the users are in, which is useful for people like me, where syncing the users in to my app, I am able to filter out users a person is friends with but not in the same server connected to my app.

I am sure there are plenty of other endpoints in version 1 that contains data that is not yet in version 2, so it would be nice if we could document both?

I'll add the /api/v2/friends endpoint soon, if you decide you do want to support version 1, then I can help document as much of it as I can.

I would love to support every version of the API that Plex exposes. Go wild!
