	Two of the gimp-perl scripts used to call gimp_layer_delete() after
	gimp_image_remove_layer(). This will fail since the layer is already
	scheduled for destruction by removing it from the associated image or
	by deleting that image. It is thus dangerous and superfluous to export
	this feature through the PDB. The gimp_layer_delete() is hereby
	obsolete and does nothing any longer. I have removed the code calling
	it from all over the place (it was commented out in almost all places).

	The PDB help for gimp_channel_delete() now explicetly tells the user
	about the proper usage of the procedure.
