Save fl_file_chooser directory on cancel (STR 3225) (#110)
* save fl_file_chooser directory on cancel (STR3225) by default, the fl_file_chooser() starts in the current directory if no filename is given, but the directory is reset to the "system directory" if the dialog is cancelled without choosing a file. This patch saves and restores the directory if no file is chosen. See also https://www.fltk.org/str.php?L3225 * add fl_file_chooser() reinitialization comments
