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


PlexGDM:
loosely based on hippojay's plexGDM:
https://github.com/hippojay/script.plexbmc.helper... /resources/lib/plexgdm.py


Plex Media Server communication:
source (somewhat): https://github.com/hippojay/plugin.video.plexbmc
later converted from httplib to urllib2


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