[scripts/init] split into separate scripts

- init.py:
    - generate initial extractor module code and test result file
    - insert new entries into modules list and site names
- generate_test_result.py:
    - generate test result for a given URL
    - insert it into the test result file generated by init.py
      (or an already existing one)
