- added basic Query object to support more complex ORM use cases (LEFT OUTER JOINS at the moment)
- added trivial unit tests for query object + run_test.py executable to launch them
Warning: this is very basic and was only done as a low-risk fix to introduce support for OUTER joins in some cases.
This will need to be improved and extended a lot to be really useful -> targeted for after v6.0...
