PSA was monolothic, now split, with new features, like a DB-backed partial pipeline. FB OAuth2 version also upped. Partial pipelines don't get cleared except when necessary. They persist for special cases like change of browser while still mid-pipeline (i.e. email validation step). Refactor, cleanup, and update of a lot of small things as well. PLEASE NOTE the new `social_auth_partial` table.
