support python3

[Steven Hardy]

Test and fix any python3 incompatible code, so folks who want to use the tools on python3 only platforms can if they wish.

I've started porting heat-cfntools to Python 3 in here https://github.com/hroncok/heat-cfntools

[Miro Hrončok (churchyard)]

I've managed to port the code so the tests pass on Python 2.6, 2.7, 3.3 and 3.4. However, i didn't run the commands themselves, I'm afraid I have no idea what that is even doing :D

Steven, could you please look at the rest? Thanks

Is there an ETA for the new release with python3 support?
