Disable Slack Wysiwyg
UPDATE (2019-12-18): The script this extension is based on no longer works (you should use the no markup setting instead). Slack used to have the ability to use markdown in their text. This extension fixes that.

Disables Slack Wysiwyg 'Feature'.
Slack used to have the ability to use markdown in their text. They changed this permanently for all users without the ability to go back. Per Arthur O’Dwyer on his blog entry that was posted on [Hacker News](https://quuxplusone.github.io/blog/2019/11/20/slack-rich-text-box/) on 2019-11-20):
> Slack has just recently rolled out a “WYSIWYG text input” widget to its Web browser interface. (Apparently, the phased rollout started at the beginning of November 2019, but it’s just now starting to hit the workspaces that I participate in.) The user experience of using this new input method is really, really, really bad.
