Source attribute does not work on field.Collection

[RaymondCarlaw]

Fields = field.Collection(field.String(), source='ActiveFields')

this code does not recognise the source attribute and will only serialise/marshal the default property name 'Fields'.
I tried using name instead and it suffers from the same problem.

Hi @RaymondCarlaw

Sorry to the terribly slow response. Had a break from a few things and the notification for this slipped through the net. Im looking to start putting some effort into Kim with some ideas for new features so wanted to reach out and see if you were still having trouble with this.
