Does not work on Python 3

[whaleygeek]

I have not made this Python 3 safe yet. Most of the imports for things like thread etc are done, but the import rules changed in Python 3 for sub packages and parent packages, and this needs making Python 3 safe.

The code is only tested on Python 2.7 at the moment.

As per issue 8, I hope to do some work on this before the end of 2014

Well, I never did get round to doing this, and it's now 2017!

I spoke to @martinohanlon and we might update this to Python3 to support mods for the new edition of AdventuresInMinecraft.

The issue really is to bring in the latest PySerial 3.x and change the API so it handles unicode correctly. If you look at the bitio project, this does just that and it works fine, so really all we need to do is retro-fit those changes.

Also note that in the bitio project the portscan is a bit more modular, being a sub package inside the 'microbit' folder - it might be nice to also cherry pick those changes over to here too.

Package imports in bitio are also sorted for both python 2 and python 3

So, this would be the comparison point to cherrypick from...
