Mutation actions (also used the undo or redo list)

For the undoredo, we use the partial checkpoint/ (Berlage, pg16) strategy to store just the components of the state that change.

Note that the update direction is only a hint for moving the cursor (mainly for undo purposes); the insertions and deletions are always applied Forward.

Note that keeping the text does not cost much: we keep the updates in the undo list; if it's a Delete it means we have just inserted the text in the buffer, so the update shares the data with the buffer. If it's an Insert we have to keep the data any way.
