	* themes/Default/images/stock-channel-24.png
	* themes/Default/images/stock-layer-16.png
	* themes/Default/images/stock-layer-24.png: new icons provided by
	Jimmac.

	* themes/Default/images/stock-eye-12.png
	* themes/Default/images/stock-linked-12.png: tiny visibility and
	linked icons that I created from Jimmac's small versions by
	scaling them down. Should probably be redone.

	* libgimpwidgets/gimpstock.[ch]: allow to register multiple sizes
	for the same stock_id. Added new icons.

	* app/core/gimpchannel.c
	* app/core/gimplayer.c: set default stock_ids so the new icons are
	used when layer previews are disabled.
