Allow assigning functions in ListElement

As an alternative to using eval with a string. This allows code
such as:

// model
ListElement {
    action: function() { doSomething() }
}

// delegate
MouseArea {
    onClicked: model.action()
}

[ChangeLog][ListModel] Support assignment of function declarations
in ListElement, to allow for models with actions.
