Removed the "Backbone Conventions" comment

The routes described underneath that comment are not "Backbone conventions", as far as i'm able to tell. Backbone conventions would be more like
```
GET      : /:collection      => findAll()
GET      : /:collection/:id  => find(id)
PATCH    : /:collection/:id  => update(id)
etc..
```

e.g, it uses HTTP verbs on whatever the root url of your model collection is (with the model ID appended after a slash) by default. There's no `read`, `create`, etc. in the way URLs are built by default.

The way Sails is set up kind of looks like old school Rails conventions maybe? I couldn't say, it's been a while since I've used Rails.
