* CSimulatorInfo only initialized once and not over and over again in plugin info
* getSimulatorInfo() no longer virtual, as we can access the member CSimulatorInfo directly
* display exact simualtor in FSX/P3D driver
* renamed to identifierToSimulator and fixed typo "Identifier"
The following issues were fixed
* Fixed wrong/missing namespaces
* Fixed obvious typos in documentation
* Documentation not in sync with source code
refs #544
* simulator common, many members now private (info -> read only)
* renamed printDirectPlayError -> logDirectPlayError
* (re)added ASSERT for FS9
* removed parent from listener (with parent no moveToThread)
* removed QFuture / QConcurrent as we have agreed to do
* unloading a plugin no longer automatically restarts all listeners
this allows a user to set one particualar simulator in the GUI and ony wait for that
* stop listener from own signal
* Added new "identifier" attribute in JSON metadata files
* "identifier" is now the one that makes plugins unique
* "name" attribute is a human-readable name
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
