draft for review

@mhoeber , @cahrens , @explorerleslie , @srpearce please review and comment, did I miss anything in the release that should be included?
@explorerleslie, unfortunately since we "designed in the browser" the final UI and visual states of the outline, there are no static comps for the finished outline. The closest documentation (for the outline only) is here - https://edx-wiki.atlassian.net/wiki/display/UX/UX+-+838+%5BVIZ%5D+Manifest+visibility+status+on+the+Course+Outline+v2.

*But* here are a few screengrabs from my local instance of both outline states and unit states:
