* Fix Runkit tags not being activated when comment is added
* Runkit tag activation was ran once, on page load. I've changed it to
run on on comment preview and submit.
* It was necessary to add a check to skip already activated Runkit
tags. The code didn't take into account that a tag could be already
processed, and would just crash.
* Fix Runkit tags and add tests
* Add test for previewing article with Runkit tag
* "Fix CodeClimate not finding waitForRunkitAndActivateTags()
* Refactor a test for readability
* Make Rubocop happy
* Improve test for previewing article with Runkit tag
* Use one method for determining active Runkit tags
* Defer loading of JS from embed.runkit.com
* Add utility function dynamicallyLoadScript(url)
* Switch to dynamic loading of Runkit
* parsed content code block is also hidden now to avoid displaying <code /> block before runkit iframe loads.
* Fix Runkit test
* Remove Runkit script caching in v2 form
* Use <%== instead of .html_safe in v2 form
* Update app/assets/javascripts/utilities/dynamicallyLoadScript.js
