Added ability to combine multiple CBZ into one files (#960)

* Added basic CBZ combine func

Need to add support for epub and maybe mobi.

* Removed irrelevant code for CBZ file fusion

* Fixed false description

* Removed irrelevant code

* Removed redundant code

Replaced page tracker and os.rename with os.renames. Removed unneeded reference to gui. Changed mkdir to mkdtemp.

* Made folder and cbz work together

You can select multiple folders of images, multiple cbz files, and folders with subfolders. Fusion will combine them all together at the same time. Mainly added this to idiot proof it.

* Updated gui

Removed redundant tooltip

* simplify code

* fix merging chapter folders with .

* uncheck fusion message
