Minor fixes (logged messages, service name)
File attribute on setup made optional
Converters can be private classes
Fixed deadlock caused by exception thrown from logic.init()
service-stop by default stops all slaves, handled missing lifecycle
Debug option and explicit slaveIndex in scripts
Setup properties are evaluated on each node individually
* added slaveIndex as built-in setup property
* renamed the built-in properties to shorter form
Evaluator accepts environment variables in form ${env.MY_VARIABLE}
