Review request for Okular.


Description
-------

Add undo / redo support for forms. Along with the previous annotation undo support I believe this completes the implementation of undo/redo for all document editing actions in Okular (Bug 177501). This review request corresponds to the "Undo/Redo support in PDF forms" feature in the 4.11 feature plan (http://techbase.kde.org/Schedules/KDE4/4.11_Feature_Plan)

Potential issue: If the last form or annotation that was modified is outside of the document viewport we are not currently moving the viewport to the form or annotation and so it can be unclear what has been undone.  I would appreciate suggestions on whether we should add this viewport shifting and, if so, how best to go about implementing it. 


This addresses bug 177501.
