proposed patch against git master

I was bothered by the fact that the arrow keys only have an effect of changing the page when the view is in "Best Fit" mode. I found this to be too restrictive. For instance, consider the common use case of viewing PDF presentation slides. If not having zoomed in and not having a very small window, it's likely that each slide will be displayed as a whole without any in-page scrolling. However, if you're not in "Best Fit" mode, you won't be able to go to the next slide using the right arrow key.

Therefore, I put together a small patch that extends the conditions on which an arrow key press will trigger changing pages. It basicly checks if the respective arrow key would be useful for in-page scrolling. If not (e.g. the whole x-dimension is shown, there is no scroll bar), evince will turn the page instead of ignoring the key press.

Any thoughts?
