Assert.Contains on a Ship formats the whole entity graph on failure and overflowed the stack, aborting
the test run instead of reporting red; the new tests check membership with a boolean and a message. The
cockpit-kill test now gives the target a hull the blast also kills, the case where the double Death
actually occurred.
