Option to add multiple values of the same attribute in the SmartNodeSelector

[lindjoha]

Problem:
When filtering on multiple values of the same attribute, the filter will return nothing sinces it's returning the intersection of the filters. The wanted behavior is to take the union of values of the same attribute, and the intersection between different attributes.

Suggested Solution:
Possibility to select multiple values of the same attribute without adding them as separate filters.

@lindjoha #222 might possibly be the solution to your use case. If that is the case, please consider closing this issue.

I have checked in the demo app and the SmartNodeSelector now has the wanted behavior. Very good!
