moved App::DBIx dump_query code block into new App::Utils class, and moved the App::DBIx query() & dump_query() methods into new DBIx class, in same file as App::DB
patched App::DBIx dump_query() method to handle INSERT statements; substitutions can be performed directly on $sql inside dump_query() without requiring separate $str variable as the function receives a copy of $sql var not a reference to it
implemented Local::Utils dump_query function, and a package (App::DB::Result) to overload DBIx::Simple::Result, but its functions are not available to App::DBIx, possibly due to Feature::Compat::Class limitations
