BUG: gateway.getObjects("FileAnnotation") slow down preformance

[atarkowska]

getObjects should link original files in the first call, otherwise every time FileAnnotationWrapper? is making separate query.

class FileAnnotationWrapper (AnnotationWrapper):
    """
    omero_model_FileAnnotatio class wrapper extends AnnotationWrapper.
    """

    OMERO_TYPE = FileAnnotationI

    def __loadedHotSwap__ (self):
        """
        Checks that the Annotation's File is loaded - Loads if needed. 
        """
        if not self._obj.file.loaded:
            self._obj._file = self._conn.getQueryService().find('OriginalFile', self._obj.file.id.val)

To load specific annotation type, there is the method loadSpecifiedAnnotations in IMetatada, it is also possible
to include/exclude some name spaces
e.g. pseudo-code

ParametersI po = new ParametersI();
if (userID >= 0) po.exp(omero.rtypes.rlong(userID));
List<String> toInclude = new ArrayList<String>();
List<String> toExclude = new ArrayList<String>();
if (nameSpace != null) 
toInclude.add(nameSpace);
if (FileAnnotationData.class.equals(annotationType)) {
//for info  FileAnnotationData.FLIM_NS = omero.constants.analysis.flim.NSFLIM.value;
  toExclude.add(FileAnnotationData.COMPANION_FILE_NS); 
  toExclude.add(FileAnnotationData.MEASUREMENT_NS);
  toExclude.add(FileAnnotationData.FLIM_NS);
  toExclude.add(FileAnnotationData.EXPERIMENTER_PHOTO_NS);
}
IMetadataPrx service = getMetadataService();
service.loadSpecifiedAnnotations(FileAnnotation.class.getName(), toInclude, toExclude, options));

In that case the file annotations+original files will be loaded.
