* Added members_payment_events table
This table will store successful and unsuccessful payment attempts, and
can be used to calculate gross volume over time.
* Added members_login_events table
This table can be used to audit member logins
* Added members_email_change_events table
This table will allow us to store a history of email addresses associated with a member
* Added members_status_events table
This table will allow us to track the change in status over time for members, as well
as calculate aggregates over time, e.g. paid members over time
* Added members_paid_subscription_events
This table will allow us to track subscriptions changes for members, as well as
calculating MRR over time

- Changing unique constraint from slug to slug+type should allow for posts and pages to be created with the same slug
- The constraint will be present on application layer for API v4 while we figure out how to deal with it in API v5

This allows us to backfill the data for testing purposes as well as for
use by existing sites. The mechanism for determining the date of an
unsubscribe event is crude, we use the date of the last update, which we
might expect to be _sometimes_ correct, but not always. We store the
`source` as NULL for unsubscribes as we cannot determine that with any
certainty whatsoever.

This value is nullable from the Stripe API so we're making sure that we
can store exact values locally.
SQLite3 does not supports altering columns so instead we have to:
1. Create a temp table and copy the data to it
2. Delete the original table
3. Recreate the original table with the necessary modifications
4. Copy the data from the temp table
5. Drop the temp table

This flag will allow us easier filtering of members via the API
* Added status column to members table
This flag will be used to determine if a member is free or paid, rather
than relying on joins with the customers and subscriptions tables.
* Added migration to populate members.status
As we add the column with a default value of "free" we only need to care
about the paid members here. We also preemptively handle migrations for
SQLite where there are > 998 paid members.
