change logger interface to not return errors (Refs #50)

Browse Source 
See https://github.com/go-kit/kit/issues/164 for discussion of why
kitlog returns an error.

```
Package log is designed to be used for more than simple application info/warning/error logging; it's suitable for log-structured data in an e.g. Lambda architecture, where each invocation is important. I agree with you that if we were doing only application logging the error would be more noise than signal. But the scope of the package is larger than that.
```

Since we are doing only application logging and we're not checking
errors, it is safe to get rid them.
