Add a print button to the toolbar

Print the document from the toolbar or via Ctrl-p using the
ev-print-operation backend. This is different than the Print dialog from
the browser, which has a NPAPI interface to pass back a block of
PostScript. That doesn't seem to be working from firefox, but this usage
is probably what people typically want anyway (print the document rather
than just what appears on the web page).
