Updated the 'feed' translation

We don't really have a word for "Feed" in Romanian, which I suppose it's why you marked it as incomplete. 
I have never heard or seen anyone use the "Flux Web" naming before, everyone uses "Feed", but since there's an article on ro.wikipedia.org (even though the page for RSS uses the 'feed' naming) for it ... there we go, best of both worlds. I suppose.

I can remove "(Feed)" altogether if you'd like, but I doubt many will know what "Flux Web" means without searching Google first.
