Enable scrolling between chapters

[kingjon3377]

In other readers (I use FBReader and CoolReader), upon reaching the end of a chapter in an ebook, if I continuue scrolling down, I will immediately see the beginning of the next chapter. Similarly, if I scroll up from the beginning of a chapter, I will find myself at the end of the previous chapter. It's awkward to have to switch to the table of contents, select the next chapter, and switch back.
