Fixes for README.md

This fixes the paragraphs for Social Account instructions. The markdown parser of GitHub seems to require a paragraph or title directly before a list, otherwise layouting doesn't work properly. This commit contains those fixes. Logo images are now all using wikipedia's dynamic resize API, so they are now matching in size.
