The following issues were fixed
* Fixed wrong/missing namespaces
* Fixed obvious typos in documentation
* Documentation not in sync with source code
refs #544
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
* Start index 10 instead 0 for CValueObject (easier to detect bugs)
* Fixed wrong indexes
* Asserts in CPropertyIndex
* Used Icon instead of QPixpmap with indexes, icons are sortable and have a tooltip
* Removed redundant toQVariant methods
* renamed fromQVariant to convertFromQVariant, the "from" methods imply the object is changed (fromJson, fromString ..)
* implemented fromQVariant - changing the object by QVariant
* moved toQVariant into PQ template
* free function setFromQVariant
