Add Work Center to W/O Processing

[VortecCPI]

Okay... I believe I am close to having this wrapped up. All the work I have done is in the context of 4.14.1 but the changes are easy enough to see and reconcile with the newer scripts.

Do we know when 4.15.1 will be released? If it will not be for some time I will add and test my changes in a current GIT instance prior to 4.15.1 release so perhaps we can release this work with it. Perhaps Phil's Employees and Timesheets feature will also be ready? I see these scripts update workorders.costissued as do my new scripts so together we should be able to track both WC overhead and WC labor.

Is anybody using Work Orders and Work Centers able to give me a hand with checking?
