remove user#index

The following exists in our API documentation:

![everydayhero_api__users](https://f.cloud.github.com/assets/486512/1569843/6147a2f2-50d7-11e3-8c81-aff8739e92b6.jpg)

But it doesn't seem to have existed in passport OR supporter. These are the V1 routes for passport:

```
        api_v1_me GET    /api/v1/me(.:format)           api/v1/users#show
                  PUT    /api/v1/me(.:format)           api/v1/users#update
  api_v1_branding PUT    /api/v1/branding/:id(.:format) api/v1/branding#update
                  DELETE /api/v1/branding/:id(.:format) api/v1/branding#destroy
```

These are the V1 routes for supporter:

```

     api_v1_charity GET   /api/v1/charities/:id(.:format)              api/v1/charities#show {:format=>:json}
   api_v1_campaigns GET   /api/v1/campaigns(.:format)                  api/v1/campaigns#index {:format=>:json}
    api_v1_campaign GET   /api/v1/campaigns/:id(.:format)              api/v1/campaigns#show {:format=>:json}
          api_v1_me GET   /api/v1/me(.:format)                         api/v1/users#show {:format=>:json}
                    PUT   /api/v1/me(.:format)                         api/v1/users#update {:format=>:json}
                    GET   /api/v1/me(.:format)                         api/v1/users#show {:format=>:json}
                    PUT   /api/v1/me(.:format)                         api/v1/users#update {:format=>:json}

```

So basically we can't have details for endpoints which do not exist, so I'm removing it.
