* Prior to this commit, images were only managed when being an image
field. No widget were used either.
* After this commit, image stored in model as url (as res.country.image_url)
can be used when specifying ':image' after the field name. The fields are
now rendered using their corresponding default widget. If there is a need
to force another widget and if the developer is sure that it is compatible,
he/she can specify it using the notation: 'field_name:widget_name'.
