DEV: enable frozen string literal on all files This reduces chances of errors where consumers of strings mutate inputs and reduces memory usage of the app. Test suite passes now, but there may be some stuff left, so we will run a few sites on a branch prior to merging 2019-05-03 08:17:27 +10:00			`# frozen_string_literal: true`

FIX: allow multiple secondary emails 2017-12-21 12:30:26 +00:00			`class ChangeUserEmailsPrimaryIndex < ActiveRecord::Migration[5.1]`
