- A error_strerror function() has been added to translate between error codes and their description.

- The error codes have been remapped and combining error codes is now done with a PLUS instead of an OR as error codes used are negative. - Descriptions to all error codes have been added. - Generation script for error.c has been created to automatically generate error.c from the available error definitions in the headers.
