Suggestion: exclude files with regexp filters in QDirModel

It's not possible to define an exclude pattern, e.g. don't show "*.o" files in a QTreeView using QDirModel as backend. It would be nice to use a regex and choose to either include or exclude files matching the pattern.

For example, to include all files matching pattern:

model->setNameFilters( QRegExp( pattern ) );

To exclude all files matching pattern:

model->setExcludeNameFilters( QRegExp( pattern ) );
