Adds an option to enable RiveScript documents to override the concatenation character on a file-scoped basis. Valid examples are: ! local concat = none ! local concat = space ! local concat = newline The default is 'none'. This affects which character is used when a line has to be concatenated via the ^ command.
Add two exportable constants that contain the error reply text for when a trigger isn't matched and when a reply wasn't found. This will make it easier for programmers to add special handlers for these without needing to hard-code the error text into their programs.
