Add a list of links to each available language for a particular page so that it gets picked up by search engines.
Remove console log that was dumping a bunch of irrelevant text.
Add language code into the top html element so that search engines have an easier time determining page language to show on relevant search result pages. I _think_ this should help people find the page in their own language using e.g. google.de instead of google.com.
Some updated German translation strings; still plenty to do.
