/*!
    \class Utils::ParameterAction

    \brief Intended for actions that act on a 'current',
     string-type parameter (typically a file name), for example 'Save file %1'.

    The action has 2 states:
    \list
    \o <no current parameter> displaying "Do XX" (empty text)
    \o <parameter present> displaying "Do XX with %1".
    \endlist

    Provides a slot to set the parameter, changing display
    and enabled state accordingly.
    The text passed in should already be translated; parameterText
    should contain a %1 where the parameter is to be inserted.
