hack up vsctool to work with python 2 and 3

StringIO does not exist any more in python3, yet requiring 2.7 would
not pave the path forward, so try to be compatible with both.

Works for me on Python 2.7.9 and Python 3.4

I would appreciate if someone more fluent in serpentinous programming
language reviewed and/or rewrote this.
