v0.3.8

Fixed

• Fixed App#refresh_cmd() to also copy Cri's default_proc to the new Hash for the command options.
• Fixed to check for non-strings for JSON & URI.
  • For JSON, convert StringIO to string in DictScraper.scrape().
  • For URL, convert URL using URI() because URI.parse() will crash with a non-string (URI object) in Scraper.open_url().
• Fixed to scrape multiple HTML Ruby tag words (instead of just 1).
  • I thought multiple Ruby bases/texts (<rb>/<rt>) were invalid, but after running into the article below and checking the HTML with a validator, it's actually valid HTML:
    - https://www3.nhk.or.jp/news/easy/k10012759201000/k10012759201000.html
    - No previous articles/URLs ran into this problem (would have raised an error), so it should only be a problem with this specific, new article.

Changed

• Formatted/Linted all code using RuboCop.
• Updated Gems.
