patch to fix leak and binary mode on windows

[Pierre Joye <pierre.php%gmail.com@localhost>]

hi,

Here is two patches against 0.9.3:

- fix leak, archive comment is not freed on close
- force binary mode on windows in zip close (you will have to add a
def for Windows, I use WINDOWS in this patch), it is required as the b
mode is ignored (or can be)

Cheers,
