[Py2exe-users] Add support for Python 3.7

[이 정훈 <jeo...@li...>]

Hello everyone.​
​
I've written code to support Python 3.7 for py2exe.​
I'd like to make a contribution with it. Is there anyone to maintain here?​
I would appreciate if you help me to merge it into the repository.

Best regards,
Jeonghun
