Some links lead to Swedish page when viewing in English

[Benjaneb]

Firstly, the delta logo in the top navbar leads to the main page in Swedish instead of English when you are viewing the website in English.

(Fixed in #80) This also happens with all three of the filtration links in the left navbar of the news page. With the filtration links, the already have ?itemType=POST or ?itemType=EVENT so it will not be possible to simply add ?lang=en on top of that. Instead, I noticed appending &lang=en to the URL works.
