* [ArchSketchObject / Window] Links of Window to support Individual Hosts
Currently, Links of Window's Hosts property (and in generall all properties other than e.g. Placement) is shared with its Linked Window object, i.e. all Windows Links instances can only has a common Host(s) which is not flexible for the purpose of Links.
AND, at the same time, Links in linked document suffer from the 'scope' of the original Linked Window, which is in the external Document.
This commit adds feature to support:
1/ each Links instance of Windows has their own individual setting of Hosts, and
2/ it see the 'scope' of the Links in its document (rather than the Linked Window in the external document)
