	Fixed color picking (reported by jimmac on #gimp):

	* app/core/gimpimage-pick-color.c: set the returned color's alpha
	value to opaque if the drawable we pick from has no aplha.

	* app/tools/gimpcolorpickertool.c: ignore all values returned by
	gimp_image_pick_color() if it returns FALSE (which happens if we
	want to pick outside the drawable).
