Subject: [PATCH] Fixing the native Windows file dialog in Rametter-temp-fixes
 branch of GtkRadiant. 	The previous code was Plain Old	Wrong (TM) in the way
 that it handled determining which "Save as type" was	selected in the	file
 save dialog.  This change affects the function file_dialog() in gtkmisc.cpp.
 Fix has	been tested on Windows 7 when the pattern input	parameter is
 something such as	"map" and when it's null.  Will	test Windows XP
 shortly	and follow up with	another	commit if it's not working
 correctly there.

THIS COMMIT SHOULD BE MERGED INTO TRUNK	AT SOME	POINT!!!
