[WIP] New behaviour property to populate the virtual name

[shaoshiva]

Adds a new behaviour property that gives the ability to populate the virtual name with something other than the title. The value of this new behaviour property can be either a property or a method of the model.

Be careful, this new property will not affect the javascript part of the renderer that will always use the title to dynamically generates the virtual name.

To make it work with the renderer we need to rethink the way the virtual name is dynamically generated in javascript (eg. with an ajax call).

Would have done the other way around : give priority to method and then to property.

It needs to accept a closure to allow dynamic insertion of the behaviour imo.

Indeed, using closure must be possible if methods added by behaviours are not recognized by "method_exists".
That would be the only two ways to override it.

PR updated :

• implements the populate callback in the renderer's javascript (via an AJAX request)
• adds an option to regenerate the virtual name after creation (eg. to generate a virtual name with the item ID)

Todo: implement a mechanism in the renderer's javascript to observe fields and regenerate the virtual name when they change (currently only the title is observed).
