Basic bulk create and bulk update
iso formated datetime aware fields with +0000 offset should use 'Z' suffix instead
Default date/time fields now return python date/time objects again by default
Add extra tests for errors from incorrect data with multiple create/update
Test moved out of serializer.py into serializer_bulk_update
Bit of extra tidying and plenty of docs
