Short month names

[Mika]

At one point in the po file there are shortnames for months, Jan, Feb, Mar etc etc. This list is missing May, I'm assuming that is because May is already short and thus you use the same translation for fullname and shortname. This doesn't work in Finnish atleast, so it would be great if you could add a separate shortname entry for May as well.

Thanks for noticing this.
We'll add it to our list.
