first commit to 'async-history'

This pull-request just adds a new maven-module for handing history-events in an asynchronous manner. At this stage it only has something like an 'Composite' to make it possible to dispatch Events to multiple 'Consumers'.

In the test-packages you will find an simple example realized with JMS and an embedded ActiveMQ-Broker.

The second commit simply results in the fact that I could not build the 'engine-rest'-module. Tests were failing with Wink. I think this is an classloading issue and configuring the surefire-plugin to execute the different frameworks (resteasy, jersey, wink)  in different   executions for each framework solves my problem. Maybe this is relevant for you too.

Cheers
