	* app/widgets/gimplayerlistview.[ch]: added a GimpAnchorItemFunc
	and use it if it's set.

	* app/widgets/gimpitemlistview.c: removed the floating selection
	special case hack from the remove_item callback.

	* app/gui/layers-commands.[ch]: added layers_remove_layer() and
	layers_anchor_layer(). Fixed sensitive setting of the "Anchor"
	menu item.

	* app/gui/dialogs-constructors.c: use the new functions when
	constructing the layers dialog. Makes deleting and anchoring
	floating selections from the layers dialog work without hacking
	or code duplication.

	* app/widgets/gimpdialogfactory.c: added comments about dialog
	destruction in dispose().
