External Parties; Load time for global collection has been optimised

The External Parties admin library can be quite large for some customers, e.g., several thousand records.

This can result in a delay of, for example, 10 seconds, the first time the External Parties form is opened.

Also, for Web Services, this means for each Business Layer being added to the pool, the time to initialise would increase by 10 seconds, just to load External Parties.

The code to load this collection has been optimised resulting in a 10X speed increase in our example database which makes heavy use of User Data for External Parties.
