Finalize after Ctrl-C

[jmgate]

If you hit Ctrl-C while ShellLogger is running, the log file isn't finalize()d. We need some way of making sure it's possible to finalize after a crash (regardless of what kind of crash). Need some way of streaming data to file, and then be able to rebuild the JSON and then HTML for the crashed ShellLogger session.
