         Better description of bar_color parm for the ProgressMeter element and the one_line_progress_meter function
         Combo element - addition of select parameter to enable easier selection of the contents of clearing of the selection of the contents.

+        Changed the _this_elements_window_closed to use a flag "quick_check" for cheking is the window is closed.  Found that calling tkinter.update takes over 500ms sometimes!
+            For appllications that call update frequently, this caused a catestrophic slowdown for complex windows.
