Added "continuous logging" functionality.

This is useful if you're having stability troubles and/or are worried about crashes. With traditional logging you can lose your capture if the program, CAN adapter, or computer crash before you've saved. With continuous logging the file is flushed to disk every couple of seconds so you won't lose more than a few seconds of log even during a crash.
