Description

When the REEF.NET Evaluator exits, it currently doesn't print any deterministic log line. We should change this, considering two main situations:

1. The Evaluator exits its main() function cleanly.
2. The Evaluator is killed or otherwise exits abnormally due to external input.

The latter is of course especially tricky, and the solution would likely be a best effort anyhow.
