- Deprecate non-localized PropertyPanel.addProp() methods.
- Add modify*LinkDetails() methods to UiTopoOverlay class.
- Augment TVMH.RequestDetails to handle link details requests.

- Refactor hostDetails() for piecemeal construction of Properties Panel.
- Add edgeLinkDetails() and infraLinkDetails() methods.
- No lat/long suppression now done server-side. Check for trailing separator.
