[zathura] [PATCH] Also wrap when scrolling with 'j' and 'k'

[Benoît Knecht]

The scroll-wrap option used to only change the behavior of 'J' and 'K'
(i.e.  moving one page forward/backward).

Now, if scroll-wrap is true and the top of the first page is shown,
pressing 'k' will show the bottom of the last page; conversely, when at
the bottom of the last page, pressing 'j' will show the top of the first
page.
