maven/junit embedding/integration with JPA/data sources

When embedded Resin is launched inside a maven/junit task, the default behavior is to disable Resin's Alarm, which manages timeouts. To re-enable the alarm, use a '-Dcaucho.alarm-enable' on the command-line when launching Java.

The alarm is disabled in embedded cases to handle of embedded Quercus in a non-Resin container.
