Added click-to-copy. Adjusted styling.

My initial project for skunkworks didn't go super hot. Ended up being a dead-end research project. So I needed to mentally detox and decided to do something easy and satisfying.

This adds click-to-copy using [ZeroClipboard](http://zeroclipboard.org/). It also adjust the styling/layout of the emotes.

I think we technically need to include the MIT license now...?
like...
```go
fs := http.FileServer(http.Dir("static"))
http.Handle("/static/", http.StripPrefix("/static/", fs))
```
