Disable auto_focus for TinyMCE

TinyMCE triggers a focus on the window itself, which means that the
window steals focus when an attachment is created even if another Zotero
window is in front. Instead, do a manual focus in the external note
window, which is the one place I could find where we rely on it (though
there might be others).
