In this release:
- Move to normalizer-based tags/mentions/concepts - that means tags/concepts/mentions are no longer "voids" and can be edited more naturally in the editor!
- New login/register UI, much nicer homepage per Dylan's designs
- Left nav bar! This let us reorg the nav structure of the app significantly, deprecate the profile drawer (and move it next to the left nav) and make the site work at all common viewport widths
