	Make GIMP work on Win32 even if installed in a path containing
	random non-ASCII characters.

	* libgimpbase/gimpenv.c (gimp_toplevel_directory): [Win32] Use
	wide-char API on NT-based Windowses. Keep the toplevel directory
	name in UTF-8. The rest of GIMP assumes it is UTF-8 anyway, and
	for instance passes file names constructed from it to g_open().

	* app/plug-in/plug-in.c (plug_in_open): On Win32, if compiled
	against GLib < 2.8.2, convert the pathname arguments passed to
	g_spawn_async() to locale charset (system codepage). The
	g_spawn*() functions in GLib < 2.8.2 take system codepage
	arguments and not UTF-8.
