Fixes encoding based on advice from @ftao

I hope this does the trick.

The unfortunate issue is that it seems quite likely that using ipconfig for localized Windows isn't the way forward, but regardless, it's nice to have functional subprocess output and a non-crashing API :)

#17

This fails on Python 3, will have a look tomorrow... enough encoding for one day

@ftao Sorry about the stress from my side, we are fixing a very annoying bug, so I will merge+release this ASAP.

It should fix crashes, although it does not address to problems with localized cmd.exe -- so I will target another release for this purpose, possibly abandoning ipconfig all together.
