Wrapper: update groonga commands
Wrapper: update groonga commands

Added commands:
  "tokenize" (follow groonga 3.0.4 changes)
  "normalize" (this is missing...)

How to make commands list:
  $ tools/extract-groonga-commands --repository /path/to/groonga

I was going to add this change before 0.0.1 release...
