Use logger to log all the exception stacktraces instead of several Exception.printStackTrace() calls which uses the stdout

The arjuna code uses pattern e.printStackTrace() on several places in the code. This would be better to be changed for a logger would be used.

For ArjunaJTA I counted 28 (excluding tests) places where the logger is not used and I suppose it should be.

Secondary. It would be nice in case of the XAException the error code would be printed together with the exception stacktrace. I have one example where I would appreciated it for example.
It's ArjunaJTA/jta/classes/com/arjuna/ats/internal/jta/recovery/arjunacore/XARecoveryModule.java
method handleOrphan where after the xares.rollback(xid) is called the exception is printed to stdout + log does not contain the error code.
