The Fl_Native_File_Chooser class contains, under WIN32, two system-de…

…fined structures

(OPENFILENAMEW and BROWSEINFOW). This forces any application program that uses
Fl_Native_File_Chooser to include file windows.h.
This is corrected by using in the Fl_Native_File_Chooser class pointers to the 2 structures.
The changes are protected by #if FLTK_ABI_VERSION >= 10304 for ABI compatibility.
