!!! NOTE: this marks the beginning of Java 8 dependency for jpf-core compilation.
From now on, we are free to use default methods and lambdas.
added convenience Loggable and PrintStreamable interfaces that mix in the
respective fat interfaces via default methods, so that we don't have to burn
inheritance of respective target classes (they only have to provide getLogger()
and getPrintStream() methods)
added a abstract LoggablePeer so that model classes can implement Loggable with
intercepted/native logging if they provide a respective concrete peer.
added some more default interface method tests
