Remove obsolete ModelListJSO#setName
Streamline storage of data from "models/list"

Store only the ModelJSO returned from the call to "models/list" in
DataManager. This will allow one API to access not only "name" and
"id", but also "owner" and "date". Prior to this, individual variables,
holding the lists of names and ids, were used. This wouldn't scale well.
Add ModelListJSO methods to get owner and date

Also add unit tests for these methods.
Only allow users to delete models they own

This is a client-side fix to https://github.com/csdms/wmt/issues/77,
which will likely be left open and reclassified as a "feature."
