ReaderPaging: use document:getNext/PrevPage()

Browse Source 
instead of doing arithmetic (ie. new_page=cur_page+1).
This makes it ready to work with custom hidden flows
where these document:getNextPage()/getPrevPage() will
be overloaded to skip pages in hidden flows.

Also fix some odd issues (page truncated or with parts
duplicated) with scrolling/page turning when at start
or end of the document.
