Reviewed by Tim Horton.

To start handling PDFActions we will check to see if an annotation has
an associated action. If it does then we check to see what type of
action it is. In this patch we provide support for actions that go to
next/previous pages, the first/last pages and zooming in/out.

We already have logic for these things so this is just a matter of
hooking up the PDFActions to them. For zooming in/out we hook into their
respective functions. For any sort page navigations we can use
scrollToPage. PDFDestination navigations are handled in a similar way.

Finally, I added in some logic to take into consideration page margins
in scrollToPointInPage.
