sets (i.e. when no TypeEngine/String/Unicode type is even being used; previously it was detecting DBAPI types and converting regardless). should fix [ticket:800] - fixed oracle out_parameters, likely broke in beta6 - fixed oracle _normalize_case for encoded names, gets unicode reflection test to work - a few extra tests tweaked/unsupported for oracle
