Thank you so much @mvavrovic for making this PR! Awesome to see a new language officially supported!

@dtrapplitefarm mentioned he is planning on getting a second set of eyes on the scientific translations as a second reviewer before merge!

@Duncan-Brain Sure, especially the new animal related translations should be checked. I've only added them yesterday when I started merging your recent changes.
