Add the ability to specify which view location is being modified by adding hub.viewId

[wayfarer3130]

For objects such as studies which may have several different items opened at the same time, and/or the same item be opened more than once, the ability to specify the location or view into which the object is being opened can be required. This may be a tab number, a window, a separate area on a screen or any other way of identifying a view.
To resolve this, the suggestion is to specify a hub.viewId to identify the view into which this object is being opened. The format of the viewId shall be either a simple integer starting at 0.
A single object shall not be opened more than once simultaneously without specifying a different viewId.
Any operation not specifying the hub.viewId shall have an implicit viewId of 0.
