Cleaning up a bit in the t() calls

There were two strings which weren't really meant to be translateable but were put in t() calls anyway. This patch should clear that up. (Of course, I'm not the original author and he/you might not agree with me, but, yeah.)

Also, Danish translation is coming up about as soon as these issues I've filed have been fixed. :)

(For the record: t('') was replaced with '' and t("user/#uid/edit", array('#uid' => $uid)) was replaced with 'user/'.$uid.'/edit'. It hasn't been tested.)
