Minor cleanup in README.
Very minor README tweak.

- I use a preview plugin to make sure my GFM is rendering correctly. This change makes it more consistent with how it renders on the GitHub site.
Remove Live features (creating separate project for that) and bump to v0.8.0 with new direction.
Merge branch 'develop'
"Merge" branch 'master' into feature/walkie-talkie (keep all code on this branch for new fork)
