Configuration of the FileLister is now left to the subclasses of BrowseDialog, as the construction of a FileLister and its configuration (to show or hide directories and files) have been separated. This allows deleting the destructors of BrowseDialog's subclasses, which existed solely to delete a FileLister object constructed by each subclass. The allocation of a BrowseDialog now also implies allocating enough space for its FileLister, so remove the check for fl being nullptr in BrowseDialog::exec().
