Token auth

[jbeez]

Fixed a few issues @mstinaff

• Converted to use token authentication on the API and pulls this directly from your Preferences.xml file.
• Restored the remove functionality by redefining the PMSPATTERN var and adjusting it slightly.
• Updated Lib paths.
• Removed dependency on perl and wget so you shouldn't have to install ANY packages at all on a fresh Plex or Plexpass plugin install, just download script and run it. Now leverages the Python that ships with PMS. Requires you already have PMS installed which shouldn't be a problem if you installed the plugin. This is an Update script not an initial install script.
• Can be run in a cronjob(probably, haven't tested).
• Merged the service code from #40 pull request from @jithinvijayan and modified it a little to work with the plexpass detect logic added based on foldername found.

Looks good. Only thing I would add now would be a way to check if any users are watching plex and delay update until no active users. That way it would be piece of mind for making it a cron job and not killing someones movie or show for an update. Another script does this here - https://github.com/mrworf/plexupdate/blob/master/plexupdate-core#L180-L207

It reads the plex-ip:32400/status/sessions url which is XML listing the active sessions.
