pivy python3

[lorenz]

Dear Debian Maintainers,

As there was no work done anymore on pivy [0] I forked this project [1] 
and updated it so it now works with python3. Now I would like to make 
this package available. So maybe you can tell me what steps I have to 
make to get some nice fresh debian packages.
