routing map parser fails silently on malformed json

[ActualAdam]

I'm working on an app that is based on Suro 0.2.10. If I add malformed json to a routing map config file, Suro will not route messages to any of the sinks. I'm unable to see any errors or exceptions in my logs. Suro appears to boot just fine. I'd expect to see an error message that Suro was unable to parse the routing map.
