   TrayUiController - Controls the screen displayed when a user selects one resource
   (Director, File Daemon or Storage Daemon). It allows the user to:

   1 - Change the data that's required to connect with the resource (name, password, address and port)
   2 - Connect to the resource, and therefore see it's terminated jobs and running jobs

   Also, if the resource is a director, it allows the user to start new backup jobs or restore jobs
