MBS Xojo Plugins, version 17.4pr6

- Fixed bug with CURL's GetInfoCookieList function.
- Fixed plugin options for CURL to pass empty C string for empty Xojo string. This helps with OptionCookieFile = "" to use in memory cookie engine.
- Added StdInMBS.Echo property.
- Added RegistryKeyMBS.DeleteTree and RegistryKeyMBS.CopyTree functions.
- Added classes for CoreML.
