+ InstanceManager: Modifying some pieces of code, the Kernel now is able to ask to the
  PluginsManager about the type of a file (the PluginsManager asks to it's Plugins who
  support the file extention of the file and then, ask to such plugin wich console is
  represented). The Kernel takes such information and gives such information to the
  EmulatorManager, who now sets the new information in the correct field of the instance.

  This changes makes appear the correct icon on the InstanceManager once is displayed
  (there is still no SNES and other icons).
