I briefly looked at adding this to the Page menu, it certainly looks
possible, but it's a little beyond me at the moment. Same with
toolbar buttons. So, right now I just tried to find the least
complicated way to zoom with the mouse.

Here is a patch which allows zooming in and out using the Refresh
button. Right clicking on it zooms the page in. Middle clicking zooms
out. It's not especially intuitive, but it's simple and it works.
