Hi,

I've created a fork of talon, https://github.com/tictail/claw, in which I've removed the signature extraction that depends on ML (which I didn't use), and cleaned up some dependencies (now much less weird stuff installed). I've also started to implement some bug fixes, along with CI test suites and so on.

I've updated the regex dependency to regex>=2015.07.19. The only thing standing in the way for proper 3 support is that mailgun/flanker is used in tests, and flanker is 2.7 only.

Hi all. We've updated setup.py file to unpin regex dependency
