Split of CSimulatorPluginInfo and CSimulatorSetup

refs #404, and discussion https://dev.vatsim-germany.org/issues/404#note-8

* Changed CSimulatorSetup to use CNameVariantPairList as data. The old version was an hack and had to go, CNameVariantPairList would allow complex types in the future and can be already shown in the GUI.
* CNameVariantPairList was improved slightly in the same step
* Functions to get CSimulatorSetup from driver / context
* Removed CSimulatorSetup data from CSimulatorPluginInfo
