Datapoints - is it regular or virtual data point?

[gabrieltholsgard]

Now it is not possible to see from a JSON data point whether it is a data point for a stream or a virtual stream.
Proposed solution is to add one more field in the mapping 'vsdatapoint' such that minimal changes has to be done across the system.
Added field could be 'vstream' and the field should always be present and always set to true for virtual streams, as such data points can mainly be handled the same and were distinguishing is needed a check for this would either be 'undefine' for streams or 'true' for virtual streams.

If virtual points are pushed in another way in the API than regular points, make sure the value is a float by using api_help:any_to_float().
