    Change |pages| to be a "private" property of |PDFViewer|
    
    As suggested by yurydelendik: http://logs.glob.uno/?c=mozilla%23pdfjs&s=30+Sep+2014&e=30+Sep+2014&h=4150#c26119, this patch renames `pages` -> `_pages` to indicate that it's a "private" property.
    Accessing pages from outside `PDFViewer` should instead be done by using `getPageView`.
