New CryptLEComplete class for SSL certificate renewals; minor doc updates and corrections to DBIx-Simple-Result and dbix.t

new vars ::DB::NO_QUERY_LOGS to suppress query logging & ::DBIx::Simple::Result::STRINGIFY_DATETIME to return datetime string rather than object

added row(), column() & value() methods to DBIx::Simple::Result & DBIx::Lite::ResultSet

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)
