Pyhton 3 support for blinkstick-python

Hopefully this should cheer you up in your current state of unwellness :-)

I realised that the current blinkstick python package was 2.7 only, and should really have had python 3 support.

this is tested with my virtualenv runing 3.2 (I'll test again with the latest 3.3), but I thought I'd turn it over to you to have a play with and kick the tyres for a while…
