commit da5c1fa4c8b2f2efba0b12d7b27460c544e2473a

Added support for Django 3.1
* Some fields were removed, others were deprecated. They are now in a list of deprecation to follow. Some new fields were added like PositiveBigIntegerField that won't be tested
* monkey_patch.py has a try/except import for EmptyResultSet that was from archaic Django. Removed apparently due to compatibility issues
