enable gui to load Qt provided meta catalogs. (#360)

QTranslate::load fails to load a meta catalog if
the absolute file name is given as the filename parameter, and
the directory parameter is omitted.
It succeeds if the file name is provided as the filename parameter
and the directory is provided as the diretory parameter.

This should resolve #359.
