- Added HandleSerializedMessage to IStoneApplication (empty impl)
- Split UpdateWebApplication with "WithString" and "WithSerializedMessage" variants
- Due to the modules in TS, globals are now unallowed and the callbacks from C++ to JS are stored in the "window" instance
- Split UpdateStoneApplicationStatusFromCpp with "WithString" and "WithSerializedMessage" variants
- Split NotifyStatusUpdateFromCppToWeb with "WithString" and "WithSerializedMessage" variants
- SendMessageToStoneApplication (C++ global) has been split into SendSerializedMessageToStoneApplication and SendCommandToStoneApplication
- In WasmPlatformApplicationAdapter: HandleMessageFromWeb becomes HandleCommandFromWeb
- In WasmPlatformApplicationAdapter: added HandleSerializedMessageFromWeb
- stonegentool now handles the "json" primitive type (used, a.o., in the VSOL "EditInstance" message)
- Fixed indentation and added json serialization overloads in the stonegentool templates
- Added test of the json primitive type to testWasmIntegrated (in Resources/CodeGeneration)
- Adapted testWasmIntegrated (in Resources/CodeGeneration) to the changes above
