Linkify urls on grep page

[JamieKitson]

1. Move the link to the tweet to the datetime text.
2. Add links to urls in tweets. This can crudely be done with:

   $status_text = preg_replace(
    '/(https?:\/\/\S+)/',
    '\1',
    $status_text
   );

I always thought it was a hotbed of complexity to linkify URLs so I was always happy to defer that to twitter's UI.

I'm a bit bothered by the way the datetime text is rendered at the end of the line. Doesn't look quite right to me. Worried that if that becomes the link to the tweet, people might have more trouble that they should copying a link to the canonical URL of the tweet.

I don't want to linkify text.
