Basic Shapes: XML export/import added.

Many files were changed, so debugging required.
Minor Bug exists: 
If we export to xml first time, it is OK. But if we then add another shape and then export, then the new shape is not added in XML.
Reason: UndoAction not implemented at present for basi shape addition.
