Cover page added

I added a cover page for the this blog, to make it look a little more fancy. I'm pretty happy with how it turned out, but it's basically the Semantic-UI's layout example, but I did change some stuff. I added a background, and set the menu borders to none. The background image I used is a super gaussian blurred shot that Tuong and I took while on vacation at Maui.

All to say, I'm quite happy with what I have right now. I have done most of what I set out to do for this theme, but there's a couple of more features I want to add. I'll see if I have time to do it, and if it's worth the effort.
