Arquillian Integration Tests

[aerben]

I'm currently setting up Arquillian ITs for the server component.
The target is to let maven download and unpack a wildfly AS in the target directory and let arquillian run the server and deploy a test web-app.
See http://arquillian.org/guides/getting_started/

The wildfly-AS will be a zip-maven-dependency, so it will be cached in the local repo after clean. On travis, however, the build will take about 10 minutes as wildfly will be downloaded every time.

Done. Please have a closer look at it, especially the maven build layout. There may be some room for improvement.
ITs runs fine in IntelliJ in a reasonable time span (<60s).
