Added ',' thousands grouping to int.__format__. See PEP 378.
This is incomplete, but I want to get some version into the next alpha. I am still working on:
Documentation.
More tests.
Implement for floats.
In addition, there's an existing bug with 'n' formatting that carries forward to thousands grouping (issue 5515).
