Support adding/updating ZIP-format comments
A free file archiver for extremely high compression

7-Zip 9.20 supports reading comments from ZIP files. The attached is a low level support of updating those comments. No changes in the UI or command line switches.
The comment can be set by ISetProperties interface. The property name is hard-coded "Comment".
As in the current version, if the archive is updated and no comment is set, the one from the original archive will be used.
Note: this is not about comments, stored in descript.ion file. This is about comments that are stored within the ZIP file itself.
Initial version of the support. Patch against 9.20.
