[Feature Request] Support compressed files (.tar, .rar, .zip) as folders

[vmpajares]

Having multiple comics (cbr, cbz, cbt, cb7) in a single packed file as a folder have many advantages. You can move it easily, storing it waste less clusters and you can share it as a single file.

But YACReader can't open the packed file and show the cbx inside it. The program assume that it's a comicbook and can't find any image inside the file.

Ideally it could use the packed files as folders but I assume that this will need changes in the Library and maybe the opening of YACReader.
