Consider a loadDefaults() method in the Item base class
Created by: arbennett
As per the discussion in #233 (closed) it is sometimes desireable to provide a way to load default data to a newly created item. In the discussion it was decided that currently there's not a straightforward and correct way to accomplish this. By adding a loadDefaults()
method a part of the Item
class we coulld provide a standard way to do this.
