Implementation of ALF-5066. Support for thumbnailing of .eps files.

Had to relax AbstractImageMagickContentTransformerWorker's restriction to 'image/*' mimetypes to allow 'application/eps'.
  Added application/eps to the MimetypeMap.
  Added application/eps to the view and edit modes of the mimetype.ftl forms control.
