Replace __title__ by templates and __reprField__

[namlook]

The title template are found in <generic_model>.__title__.hbs

the title and description are defined in template via their helpers:

<h1>{{title model}}</h1>
<p>{{description model}}</p>

Other suggestion:

{
  BlogPost: {
    representation: {
      titleField: 'title',
      descriptionField: 'description',
      thumbField: 'thumb',
      geolocationField: 'geolocation',
      langField: 'lang'
    }
    schema: {...}
  }
}

In representation, the field does not necessary be present in schema. It could be a computed field on the model (for instance geolocation computed from geoLat and geoLong)

Fallback to title and description. If not present in the content, we can add/overwrite in the model

• This behavior is implemented via the helpers renderTitle and renderDescription.
• __title__ and __description__ has been renamed in title and description.
• __title__: {bindTo: <field>} has been changed to aliases: {title: <field>, description: <field>}
