main: Show traceback when we're extra verbose

Adding --verbose (or -V) flags moves the logger from ERROR to WARNING
(-V), INFO (-VV), and DEBUG (-VVV).  Additional increments were
ignored, but I don't like always masking tracebacks.  This patch sets
an additional verbosity level (-VVVV) which logs at DEBUG and
additionally prints exception tracebacks instead of hiding them.
