/** when this is defined, the code will use
* QFileDialog::getOpenFileName and friends to create filedialogs.
* Effects:
* - the dialog does not use the quick directory buttons (Button
* parameters);
* - with Qt/Mac or Qt/Win, the dialogs native to the environment are used.
* - with Qt/Win and Qt <= 4.3.0, there was a number of bugs with our own
* file dialog (http://bugzilla.lyx.org/show_bug.cgi?id=3907).
*
* Therefore there is a tradeoff in enabling or disabling this (JMarc)
