	Fix bug #134304, as far as it's fixable:

	* app/core/gimp-edit.c (gimp_edit_paste_as_new): handle pasting
	buffers without alpha. Also don't uselessly convert all buffers
	to RGB but create an image in the buffer's color space.

	(gimp_edit_extract): call gimp_selection_extract() with
	add_alpha = FALSE.

	* app/core/gimpselection.c (gimp_selection_extract): set add_alpha
	to TRUE if there is a selection, because the selection could have
	any shape.
