Better annotation, comment, conversation features

[e0d]

More involved/interactive feedback with ORAs -- it would be great (and many faculty have asked for) a way to leave comments/feedback on ORAs (essays, in particular) that students would be able to respond to, allowing for more of a conversation. Specifically with 2 and 3 (which are the same), being able to move content from one edx course to another. Improved notifications, especially when learners submit ORAs.

@Daniel-hershel pointed out that TinyMCE has a comment feature.

This could be the simplest path to making this feature available in ORA.

The TinyMCE version does support marking comments as resolved.

It do not believe it supports "suggesting mode."

Closing a duplicate ticket, but capturing a relevant comment in which @Colin-Fredericks suggests looking at Harvard's annotation tool.
