Import Sellar Credit orders to Breww before they have been confirmed in Sellar

[luke]

@dan-silver

Pull Sellar Credit orders in to Breww as soon as they’re placed on Sellar so that stock levels can be updated.

I’m splitting this part of the feature request at Sellar Integration Feature Request - Sellar Credit Customer Mapping into it’s own thread (to follow our rule of one request per thread).

If you’d like to see this in Breww, please vote for this thread.
