Comment 6 for bug 1528924

I've made some headway here, so I'm assigning myself. So far, I've been able to add and populate the circ and circ_summary(accs) columns. However the current state of the code breaks the detail view. Once I have every field, and have cleaned them up(readable dates, for example), I'll have to do a refactor of the detail view in order to take advantage of the new information being brought in.

Prior to this commit, an item in the item status itnerface was just a flattened copy of acp data. I've added ._circ and ._circSummary, both themselves flattened copies of the circ and accs data tied to the copy.
