creating a memory leak(?) that will go away with the transition of XMLNode* to
shared_ptr<>. A few bits toward restoring history from XML.

Nuke Serializable in favor of Stateful. Got rid of some warnings with stub
code.

It compiles and runs and seems to still work. Still needed is the actual
serialization. Time to merge back to trunk so things can be tested by all.

Memento(Redo|Undo)Command has a noop for the undo or redo respectively, and
we don't need both before and after state. This is primarily useful for
drag start/finish callbacks, and really only makes sense where wrapped by
(begin|commit)_reversible_command (a composite command).
Also a few more "normal" MementoCommands.

All the obvious MementoCommand grunt work. Now there's some
add_undo/add_redo_no_execute sprinkled around where one is separated from the
other (e.g. in different callbacks) or perhaps even where there's only an undo
and no redo. Also some sigc-based undo/redo pairs that probably need their own
Command class.
