Graphviz generation doesn't match command-line parameters

[ghanneman]

There seems to be some mismatching going on inside the viz command. The DuctTape help message says that unpacked is the default style -- I would assume that's the most detailed output. However, in reality it seems like a very small graph is created by default, and that a much larger graph is created by --viz-type packed than by --vis-type unpacked. Perhaps the code hooked into these two flags is reversed?

Details from actual commands below:

Packed:

$ ducttape full_system.tape -C mysystem.tconf -p large --viz-type packed viz | wc -l
