ISBN Support (#1985)

* Fixed a bug where weblinks would always show

* Started to try and support ico -> png conversion by manually grabbing image data out, but it's hard as hell.

* Implemented ability to parse out ISBN codes for books and ISBN-13 codes for ComicInfo. I can't figure out ISBN-10.

* Fixed Favicon not working on anything but windows

* Implemented ISBN support into Kavita

* Don't round so much when transforming bytes
