Previously, when TTX was run in verbose mode, the messages printed to the console would also show the time each one was logged -- e.g. "blah blah (15:23:24)" -- using the 'debugmsg' function which is defined here. Even though the logging package would allow to do the same thing (via 'datefmt' and "%(asctime)s"), I decided drop this, as I think it's not very interesting... I'll replace it with the overall elapsed time in seconds, in a follow-up commit.
