monitoring UI should display all objects in schema order

[kletkeman]

Currently, when looking at state objects returned by readAsset, readAssetHistory, readAllAssets, and readRecentStates, the monitoring UI displays all properties in each asset in alphabetical order. This is a very confusing order, since the order changes depending on which properties happen to be present. It makes it very hard to follow the progression in history, for example.

Ideally, the order would always follow schema order, which would make it easy to follow a progression of states.
