Adds a synthetic string property, generated from a definition string and other properties in the model.
The definition string, similar to how printf works, contains ${} placeholders that are replaced by the actual value of the property inside the placeholder tags when the synthetic property is retrieved. For example, a numeric property length might be strange to use as a label, since it will only display a number. However, a synthetic string can be generated with the definition "Length ${length}." which renders more nicely and does not require any more code by the user of the property.
not_ready and on_error strings can be given to be used when the data is not ready or there is some error, respectively. These strings do accept placeholder tags.
