Now when Ctrl/Cmd+S or "Save Page As" is used, Firefox will send PDF.js a message to trigger downloading. This allows PDF.js to generate a new PDF if there is modified form data that needs to be saved or send back the unmodified data. Once PDF.js has generated the blob, it will send messages to the PdfjsParent to open the "Save As" dialog. Adds two tests: 1) Saving a plain PDF without forms. 2) Saving a PDF with modified forms and verifies the new PDF has the form data.
