Add JSR-310 Support (#386) 

Add support for Java 8 Date and Time API AKA JSR-310. On the face of it
the existing JDBC types java.sql.Date, java.sql.Time and
java.sql.Timestamp offer conversion methods to and from JSR-310 data
types. Unfortunately java.sql.Timestamp does silent data truncation
when the timestamp falls into a DST transition on the JVM time zone.
Worse still for java.time.OffsetDateTime there is no corresponding JDBC
type. Therefore these conversions have to be implemented. All of this
has to be programmed using reflection so the code compiles and can be
executed on Java 7.
