* significant improvement in microformats markup This is a huge improvement and I believe will close #965. Had these microformats reviewed by others in the community to help ensure they are at least correct, if not complete. I did not want to change the structure of the page, and so there it does not fully mark up the entire ancestry chain, or reply chain, only the direct decendants and direct ancestors are correctly associated, but this is likely fine as the most important bit is to have access to the urls for those toots which are now correctly fetchable. * improve code climate * trying to pass code climate tests * code climate * fix p-summary for content warning posts * fix error introduced when merging via github
