Add hint to the snapshot builds made with every travis build and fix some typos

Check if the status field is a String and don't propagate any Exception
from the StatusUpdater, so that the application don't fail like in #120

Streamline the Hazelcast support with boot 1.3 and support storing events in hazelcast

closes #113

Due to our use of @Conditionals on our @Configuration-classes the import must be deferred, so that the classes are processed after all other @Configuration-classes

By using local.server.port, local.managment.port and ApplicationReadyEvent the port detection and ready state detection can be simplyfied in boot 1.3

But make no use of it.
