Python 3 compatibility

[LemonBoy]

When calling os.open here the octal number 0644 should be written as 0o644, otherwise python3 raises a SyntaxError: invalid token.
The same syntax works fine as far as I can see in python2.

Ok, I actually tried to use it and found you need some more adjustments.

Ah, I assumed you had tried it so I jumped the gun and added Python 3 compatibility notes in README and CHANGES. I'll revert those for now.

Here is a patch that seemingly works.

Thanks, but that patch breaks Python 2 support. You can check Python 2 compatibility by running the test suite (./test). Replace /usr/bin/env python with /usr/bin/env python3 in miniircd to run the test suite against Python 3.

@LemonBoy: Are you interested in working on properly supporting both Python 2 and 3? Otherwise, I think it's time to close the issue.

Fixed in #28.
