added hash() and array() to Local::DBIx::Simple::Result to return in list or scalar context - original only returned scalar ref, and to inflate dates in array()

adapted Local::DB to cache DBIx::Simple object for sharing between eg RequestForm app & its test scripts; Local:: sub-classes of DBIx::Lite to provide DBIx::Simple methods (hashes, arrays, map, etc); test script for Local::DBIx::Lite (broken - needs fixing)
