Previously autospec would not pick up save if you saved a plugin in a
symlinked path, this broke quite a few workflows
We now maintain a reverse map so we can correctly re-run specs in plugins
This adds the markdown.it engine to Discourse.

As the migration is going to take a while the new engine is default
disabled. To enable it you must change the hidden site setting:
enable_experimental_markdown_it.
This commit is a squash of many other commits, it also includes some
improvements to autospec (ability to run plugins), and a dev dependency
on the og gem for html normalization.
