Add possibility to individual SSP vocabularies as separate vocabularies in CME

[jakubklimek]

SSP is actually a set of individual vocabularies, which can be seen in the AL control panel. An alternative approach to accessing SSP from Dataspecer (CME) would be to be able to add individual SSP vocabularies as CME vocabularies, showing them with different colors, similar to OntoGrapher. This is currently not possible.

At the same time, this would have to be further discussed in the context of the future of SSP and vocabularies created according to "Zákon o správě dat".
