Tell HN: iCombinator back up

Hi all,

Apparently iCombinator.net has been down for the past couple of days. It should be resolved now.

I've also fixed:

- "Next 30 Stories...". Looks like this was also not working for a while. back up! :)

- Instapaper-ing HN items (such as these 'Tell HN', 'Ask HN', etc. stories) will now work. It had previously been trying to instapaper the relative iUI url.

Enjoy and sorry about the downtime!

(thanks to @stephencelis for the heads up!)
