Ticket #2608: widget enhancements.

Browse Source 
New method of widget ID assignment:
now widget ID is a value of unsigned long type. Dlg_head structure now has
new filed widget_id that contains a ID of the next added widget. When new
widget is added into dialog, widget_id is set as ID of it and then
incremented.
