- Render remote census configuration content on settings index.
- Update type method from Setting
On Admin::SettingsController#index we are using 'all_settings' to
group all settings by 'type' method.
'type' method return the first part of key when split by '.'
To allow use by example: all_settings["remote_census.general"]
and recover only settings related with this key we have added new
'elsif' on 'type' method.
