This feature is used for defer loading of images and in future for post cloaking
This gives us a polyfill so we can safely use the feature in problem browsers
The polyfill supports "polling" but it does not appear we need it yet.
If we discover anything odd here, consider setting poll interval per:
https://github.com/w3c/IntersectionObserver/tree/master/polyfill
```
var io = new IntersectionObserver(callback);
io.POLL_INTERVAL = 100; // Time in milliseconds.
```
Keeping the mutation observer cause we often mutate the DOM

Also corrects the positioning of autocomplete (when typing @ or emoji)
Previously there were edge conditions where autocomplete would be hundreds
of pixels away due to a bug measuring.
This correct an issue where Firefox ends up having an enormous blank space
at the bottom of topics after editing.
This commit removes the old evilstreak markdownjs engine.
- Adds specs to WhiteLister and changes it to stop using globals
(Fixes large memory leak)

CommonMark)

- Fixes plugin specs
This adds the markdown.it engine to Discourse.
https://github.com/markdown-it/markdown-it
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.
- Show fullscreen timeline with title of topic in mobile
