Update Top 5 JSON file

[elyezer]

Do the following:

• Improve top5 directive to output a numerated list instead of a bullet list.
• Fix a bug that the top5best was not showing the most suggested items first.
• Update the top5.json with grep'ed items from all episodes
• Convert 5 more episodes to make use of the top5 directive

Looking good!!!

@omaciel I am glad you like it. This is now ready for review, I've updated PR title and description with everything done.

After this I will send more PRs with more episodes converted to use the top5 directive.
