Added Danish translation for strings added in 1.5.0

Is this what you mean by 'vacation'? :P

I took the liberty of assuming no changes in previously existing strings, i.e. have only translated from line 167 and onwards. Let me know if my assumption is wrong.

This time I did not try so hard to preserve your exact wording (but of course the meaning of the words). This was to avoid unneccesarily long Germanesque sentences (not on account of your choice of words, but sometimes literal translations become awkward).

Why 'by vendor'? Does it matter who modified the AOSP lockscreen?
