Tracebacks are not being captured to the watchmaker log file

[lorengordon]

Easy enough to capture those in a try/except block where we are already catching the exception and logging a message just by adding exc_info=True to the log call, but would be nice to also capture the traceback for an exception anywhere... And doubly nice if we don't have to add that param to every except block where we are logging and raising...
