Move calculation of summary data to a "finally" block so we display what we can, even if there was an exception during the simulation. In particular, if the exception happened in a branch other than the sustainer branch we still get all our summary data.

Added a commented-out bit of code forcing an exception for testing purposes. Since many former exceptions are now sim aborts, there isn't a reliable way to create a broken rocket design to test exception behavior -- which is a good thing!
