links clicked in read views replace current tab

New Bedford puts html links into their transcriptions. If you click on one of the, they replace the current tab.

I can't tell if they want links to open a new tab in the overview/read views of FtP, or in the exports. (We don't support links in their favorite pdf exports right now, anyway.)

Can we update the a tags which we display to dynamically add a target attribute so that they open in a different tab when users are viewing the read_work or display actions? I don't want to do any such update in the exports, so this should just be in the xml_to_html methods.
