Collection of "connector functions" to Plex Media Server/MyPlex


PlexGDM:
loosely based on hippojay's plexGDM:

Plex Media Server communication:
source (somewhat): https://github.com/hippojay/plugin.video.plexbmc

Transcoder support:
PlexAPI_getTranscodePath() based on getTranscodeURL from pyplex/plexAPI
