Intake patch

[Peter Ledbrook <pe...@cacoethes.co.uk>]

Hi,

I have attached a patch for the Fulcrum Intake service that adds an 
option for populating mapped objects without overwriting an object's 
properties with default values. This behaviour is required for Scarab. 
Here's the log message:

---
At the moment, whenever Group.setProperties() is called on a mapped object
and a Field value is not set, the corresponding property on the object is
overwritten with a default value. This change adds two new methods that
allow Field values to be mapped to an object's properties without 
overwriting:

  Group.setPropertiesNoOverwrite()
  Field.setPropertyNoOverwrite()
