Lint

In exploring whether we could use this at my company, I ended up linting everything to document my understanding of the project and hopefully make it more approachable.

before:

```
rgarcia@raf-laptop:~/go/src/github.com/twitchscience/blueprint$ find . -type f -name "*.go" -not -path "./Godeps/*" -exec golint {} \; | wc -l
78
```

after:

```
rgarcia@raf-laptop:~/go/src/github.com/twitchscience/blueprint$ find . -type f -name "*.go" -not -path "./Godeps/*" -exec golint {} \; | wc -l
0
```
