Added ParameterAction class for QActions acting on files.

Reduce inconsistencies in tr()-Strings provided for
QActions that act on a current <something> (mostly files) by
introducing a ParameterAction class that takes the tr()-Strings
at construction time and provides a setParameter(QString) slot,
allows for setting that parameter or an empty string, which
will cause the displayed text to be updated.
