Using BusConfiguration throws NullPointerException

[nikoliazekter]

This code throws NullPointerException:

    BusConfiguration config = new BusConfiguration();
    MBassador<Object> eventBus = new MBassador<Object>(config);

Exception in thread "LWJGL Application" java.lang.NullPointerException

True. This way of construction was not meant to be supported. Either use default constructor of bus or specify full configuration object. I might reconsider this decision as it seems bad design that this code simply errors with an NPE.

I fixed the NPE and replaced it with a more meaningful error message. This is available with the 1.2.4 release.
