#74 MDB & JMS RA XA ConnectionFactory Usage

[Jason Dillon]

The ConnectionFactory usage for Message Driven Beans as
well as the JMS Resource Adapter has been changed to
use a common ConnectionFactoryHelper class, which will
ensure that if a ConnectionFactory implements an XA
interface that it will create an XAConnection.

The JMS Resource Adapter will assume that the
connection is not XA unless an XAConnection was
produced by the ConnectionFactoryHelper.

The xaTransacted flag for a Connection which is not XA
will be false (instead of always being true).
