	to GimpActivateItemFunc, GimpNewItemFunc and GimpEditItemFunc.

	* app/widgets/gimpdrawabletreeview.c
	* app/widgets/gimpitemtreeview.c: pass the view's context to
	the functions.

	* app/actions/channels-commands.[ch]
	* app/actions/layers-commands.[ch]
	* app/actions/vectors-commands.[ch]: added GimpContext parameters

	callbacks.

	* app/actions/image-commands.[ch]: made public layer merge utility
	function private and cleaned the whole file up a lot.

	image-commands.c for merge and flatten.

	* app/actions/edit-commands.c
	* app/actions/file-commands.c
