Code Issues Proposed changes

Enable flake8 E711 and E712 checking

Browse Source 
E711 comparison to False should be 'if cond is False:' or 'if not cond:'
     comparison to None should be 'if cond is None:' or 'if not cond:'
E712 comparison to True should be 'if cond is True:' or 'if cond:'

Most violations were in DB queries. Replace as follows:
  False -> sqlalchemy.sql.false()
  None  -> sqlalchemy.sql.null()
  True  -> sqlalchemy.sql.true()
