Allow -log argument for Eclipse compiler
If the -log argument is used, the resulting log file is scanned for compiler output, both text and xml formatting supported. Otherwise a temporary log file is used to capture compiler output. * Unit tests refactored * Output emitted as "INFO" are reported as Kind.NOTE * Column count adjusted to be 1-based index
