Support file save triggered from the Firefox integrated version.

Related to https://bugzilla.mozilla.org/show_bug.cgi?id=1659753

This allows Firefox trigger a "save" event from ctrl/cmd+s or the "Save
Page As" context menu, which in turn lets pdf.js generate a new PDF if
there is form data to save.

I also now use `sourceEventType` on downloads so Firefox can determine if
it should launch the "open with" dialog or "save as" dialog.
