Title: allow rendr to be mounted on nested url

Backbone.history.start can take a rootPath if you're mounting the backbone app on nested url

http://backbonejs.org/#History-start

you use this by starting a rendr sever with
```coffee
app.use rendr.createServer(appData: {rootPath: '/cool-rendr-app'})
```
