Attempt at fixing "de-dupe cover" breaking chapters

[bust4cap]

should fix #742

(also fixing general page spread alignment)

Wouldn't it be simpler to just add a offset of 1 on this line if the option is checked?

maybe i did something wrong but doing it that way if the first page is a chapter (aka "cover" for example) its instead just a copy of the last chapter again

Oh that's because the -1 index is the last item of a list in python.

e.g.

long_list = [1,2,3]
print(long_list[-1])

prints 3

So some additional logic to skip the first chapter if its only one page. Or clamp the index to zero if multiple pages.

someone more capable than me should probably take this over if another approach is preferred^^

Went ahead and opened a PR please review and test.
