Conversion to Python 3, removing the ssl bug hack and adding HotSpot feature

I don't know how we can merge 2 version of a package compatible with to different version of python. 
Does a pull request the best way ?

I also manage to force SSL to the "correct" protocol (which is unsafe actually but this how unifi work...)

And I had the 2 method for HotSpot usage (what I needed actually ;) )
