Minor adjustment of Csearch page.

```
Not really a issue. But request.

I see that "Emacs editor integration" is promimently mentioned on the homepage
of codesearch. In that case, I would recommend to add

"Vim editor integration" too, link:
https://github.com/junkblocker/unite-codesearch

Thanks in advance.

Start at the codesearch homepage and find the prominent “Emacs editor integration” mention. Add the provided Vim editor integration link alongside it, and consider the issue done when the Vim integration is visibly linked from the homepage.
