A Comic Book (cbz or cbr) is nothing more than a renamed zip (or rar) files containing images. You can create it with internal packer and renaming the file with *.cbz (or *.cbr).

This patch create a zip file (or a rar) directly with the comic book extension.

Also, we add the ability to browse these files, like Toni did in D1336.

Two new options in packer (Alt+Shift+P): cbz and cbr (if rar utility is installed).
