Title: Svbtle-style 404 redirection

Svbtle redirects to homepage with a notice. I told about this in #76. (meanwhile the notice has slightly changed, see [here](http://i.imgur.com/Mziik.png).)

I made `404.php` to redirect to `blog_url/?not_found=1` and in `header.php` showed this notice according to URL parameter. It worked good on me. This is also SEO-friendlier, handles 404s with 302s. Please merge this.

**NOTE:** Svbtle also runs javascript to remove `?not_found=1` parameter after the document is loaded, I didn't implement it because I believe we don't have any JS file yet. (maybe you can) It removes search form in 404 page (which Ricardo created), but hey, if we are on the track of original svbtle implementation, this is a step.
