  Moved error-handling to a separate class - Diagnostics. We were earlier returning errors as tokens which did not work very well when error occured while parsing a preprocessor directive. Now all returned tokens are valid. Errors are reported via an abstract Diagnostics interface. Updated unit-tests with the new scheme.
