Title: add custom prefix, refactor format and GithubHook string

Allows me to do stuff like:

```js
var githubhook = require('githubhook');
var format = require('util').format;
var github = githubhook({
logger: console,
prefix: function () {
return format('[GithubHookkkk %s]', (new Date()).toISOString());
}
});
```

```
