of a table and another join involving the same table. messed
up ORM decision making [ticket:593]
- removed is_natural_case function from ANSIIdentifierPreparer
- documented instance variables in ANSICompiler
- fixed [ticket:120], adds "inline_params" set to ANSICompiler which DefaultDialect picks up on when
determining defaults. added unittests to query.py
- additionally fixed up the behavior of the "values" parameter on _Insert/_Update
- more cleanup to sql/Select - more succinct organization of FROM clauses, removed silly _process_from_dict
methods and JoinMarker object
