Revision 740760

Fixes broken HttpServiceConfigurationTypeHandler, added extra test for the thing that was broken before.
Additionally, sets the org.osgi.service.http.port for the single-bundle distribution (this can't be done automatically for the multibundle distribution as it needs to happen before the pax-web component is started). 

The for org.osgi.service.http.port property, the following algorithm is used:
1. if its already set, don't change it
2. if not set, see if port 8080 is available and set it to that
3. if port 8080 is not available, ask the system for another free port
