positive.code: === Available Plugins Server
  The plugin manager obtains a list of available plugins from the 'Available Plugin's server'. This may also host the maven repo used to download the features.
  
  Alternatively the local Plugin Manager can list the available plugins which have been installed as bundled Plugin Kar/RPM's on the local machine. In this case, the Plugin Server URL should be pointed at the localhost. The admin username and passwords are used to access the Available Plugins Server
