Added Fl_Native_File_Chooser widget (with manolo's cocoa mods) to FLTK.

Browse Source 
* Source brought into CMP standards compliance
	* test program added (test/native-filechooser.cxx)
	* Tested with linux (Ubuntu8) and with OSX (cocoa and non-cocoa builds)

TODO:
	* Needs doxygen docs from Greg's original HTML documentation
	* Needs mods to Windows build files
	* Needs mods to cmake, and other build files
	* Needs Manolo's latest mods (from STR #2298) mentioned on and after "02:05 Jan 13, 2010"
