Alpha v1.1.0

NOT INTENDED FOR PRODUCTION USE.
See previous release (Alpha v1.0.0) for a more exhaustive feature description. This description lists only changes since that version, so assume everything the prior release's description says is true of this one unless specified otherwise. There is now a basic dark theme (needs tweaking), full CSRF protection for every form, better form logic, better error displaying, and blog posts now display author information. Overall, minor but substantial improvements in terms of security and usability.
