Wrong page order
In many CB files, the images are named like this:
1.png 2.png ... 10.png 11.png 12.png
Currently, zathura will display these in the following order:
1.png 10.png 11.png 12.png 2.png ...
That is, for comics longer than ten pages that use this (as far as I can tell quite standard) naming system, the ordering of the pages is wrong and it will mess up the reading experience.
