Improvements to the AS for older single-core, clients

We’ve made some changes to the Assignment Server to improve the ability for older, single core (i.e. not SMP) clients (pre-v7) to get WUs.  The v7 client merged the SMP and the single core clients and it (and the v6 SMP client) reports information slightly differently enough that it could lead to issues with older single-core, v6 clients getting assignments.

This is updated AS is running on the main AS and looks to be behaving well.  We will migrate it to the other AS’s shortly.
