More flexible variable wrappers (C# properties). The property set can now support a different type to that used in the intermediary layer. This is achieved by using a temporary variable and specifying the name of the temporary variable in a new 'valueparm' attribute in the csvarin typemap. Also Fix bug reported by Glenn A Watson and #1795260 where the cstype typemap used the 'ref' keyword in the typemap body. The type for the property now correctly comes from the 'out' attribute in the cstype typemap.
