Fix issue #295

The JEventSourceGenerator needs to pass a JApplication pointer to the JEventSource constructor. However this pointer needs to be injected into the generator first. I'm hoping to get the JApplication pointer out of the EventSource constructor completely, and move all initialization logic into Init() instead.
