	* plug-ins/common/file-gbr.c: let the save procedure also accept 
a
	grayscale layer with alpha channel, as we do in the GIH save
	procedure.

	* plug-ins/common/file-gih.c: when loading a brush mask pipe,
	create grayscale layers without an alpha channel. Changed the 
save
	procedure to also accept layers without alpha channel.
