Correctly render all supported markdown on new Reddit

[iampueroo]

Updated Status: All markdown has been implemented! 🎇 Currently, the changes are only on master and on the development extension. After testing (i.e. me using REddit this week) to ensure there aren't any bugs, I will publish the updated the changes to Firefox and Chrome on Thursday, May 20th.

Due to the way the new reddit stylesheets work, special markdown formatting is not supported out-of-the-box. For example, even though the HTML returned by the Reddit API has a <strong> element, it does not get bolded correctly since the default stylings of these elements are removed globally on the page, and are implemented via obfuscated classes that I cannot use.

This issue aims to ensure that all markdown that is supported by Reddit renders correctly in the rComments popup.
