	* libgimpbase/gimpenv.c
	* plug-ins/helpbrowser/helpbrowser.c
	* plug-ins/imagemap/imap_preferences.c: use g_build_filename().

	* plug-ins/script-fu/script-fu-scripts.c: use new GDir functions,
	g_build_filename() and g_file_test() to make code more portable.
	Don't use deprecated gdk_font functions. We don't use X fonts any
	longer.
