Move Fieldmapper API call to Application.pm
Move export of opensrf.open-ils.system.fieldmapper API call from
    Fieldmapper.pm into Application.pm with the rest of the shared API
    calls.  This allows us to remove the OpenSRF::Application base from
    Fieldmapper, which was causing some method name collisions.  For
    example, if a Fieldmapper object had a field called "session", which,
    incidentally, is also a method of OpenSRF::Application, the version
    from OpenSRF::Application would get called instead of the Fieldmapper
    version, since Fieldmapper methods are defined during AUTOLOAD.
    Hilarity was guaranteed to ensue.
