page up, page down when reading comics

[ranousse]

I use sxiv to view images and to read comics (a directory with about 40 images).
I discovered it yesterday and I already like it very much.

I have one suggestion.
The default behaviour of space key is perfect to view images but a bit annoying when reading comics.
I would prefer the following behaviour

1. if you are at the bottom of the page go to next image
2. else go to the bottom (or better scroll one page)
   It's the default behaviour of many pdf viewers.

Moreover I don't think it would be annoying when we only look at images (else we could also use another key, pagedown for instance).

What do you think of this suggestion? Do you think it is easy to implement?

Remark 1: I know we can use a combination of space and J but I would prefer one key.
Remark 2: Is it the right place to post suggestion? Or is this section intented for bug report?

Thanks for this great work!
