remove IRouteMessages
add support for mapping to multiple endpoints
Fixed the failing acceptance test
The message router now guards against routes with undefined addresses
Adding a test that shows the issue with routes needing to be updated
Ensuring conventions are set before doing any routing registration.

Appending addresses to event messages, except if subscribetoplainmsgs has been set and if it is fallback to override mode for events.
Merging latest in.
Added Indu's acceptance test
