* Use hidden "edit" property for "recall" operator.
* Bugfix: "Z Function" was mixing up div_x and div_y

* X,Y,Z Function Surface (by Ed Mackey & tuga3d). See http://wiki.blender.org/index.php/Extensions_talk:2.5/Py/Scripts/Add_3d_Function_Surface for examples.
* Renamed old "3D Function Surface" to "Z Function Surface".
* Align the geometry to the view if the user preference says so.
* Store recall properties in newly created object. (only usable in combination with "Recall object operator")

* Made "url" mutli-line (not as nice, but I aim for PEP8)
* Added gitorious link in comments.
