Python3 support
I use b extensively in my own work, and since hg on archlinux was recently moved to python3, I've had to update the extension.
It is not finished, and the tests don't all pass yet, but it is usable for most of what I do with issues (add, resolve, rename, list).
Since I cannot work with the heptapod repo here is a link to what I have so far:
https://hg.sr.ht/~kragacles/b/rev/521a7e144ce70779365f51bd35d0c86ebfd9f893
I won't claim this is pretty at all. But I'll aim to get the tests working soon.
