This patch completes the support for the ReturnValues parameter for the UpdateItem operation. This parameter has five settings - NONE, ALL_OLD, ALL_NEW, UPDATED_OLD and UPDATED_NEW. Before this patch we already supported NONE and ALL_OLD - and this patch completes the support for the three remaining modes: ALL_NEW, UPDATED_OLD and UPDATED_NEW. The patch also continues to improve test_returnvalues.py with additional corner cases discovered during the development. After this patch, only one xfailing test remains - testing updates to nested document paths, which we do not yet support (even without the ReturnValues parameter). After this patch, the support of ReturnValues is complete - for all operations (UpdateItem, PutItem and DeleteItem) and all of its possible settings.
