Use swagger-ui library instead of compojure-api subset to generate swagger docs

[ccjoel]

I'm thinking this is low priority right now. We're not actually using compojure-api to its full potential. right now its kinda bloatware since we import a whole lip to generate swagger docs, while compojure-api includes everything you need to make a restful API.

We didnt know of this library and we're working with compojure by itself, with liberator for resources and http statuses. I do like liberator because it makes a lot of decisions for us, so thats fine.

When we tried to use swagger-ui it kept crashing for dependencies. So we went with compojure-api to generate these.
