Lat/long parser cannot parse " 55,681192, 12,576282"

I got " 55,681192, 12,576282" by copying the coordinates listed at http://www.openstreetmap.org/browse/node/311470440 - changing the commas in the coords makes it parse fine, but I figure we should probably handle the case where people copy straight from OSM as well. (It might be using Danish decimal notation due to it detecting that I prefer Danish in my HTTP headers, but others might have comma decimal notation as well, and I also know I'm not the only Dane on the site (even if I sometimes feel like it...).)
