Adjusting INSTALLED_APPS to be a list for easier local customization
Silencing warning, logging.warn() is deprecated

Making email validation mandatory
Usability, autofocus username on login pages
Auto-verifying staff users

   - Moving to email verification with allauth is a bit precarious
     as it turns out.  Once you flip the verification to mandatory
     users that aren't verified have to verify.  Wrote a data
     migration to do this automatically for our staff users so there
     isn't any disruption to their ability to login to the admin.
Changing str for Membership
Removing edit option for PSF list, pointless
Removing unused import
Send subscribe email on membership

  - A bit hacky but we're going to automatically send a subscribe
    email to psf-members-announce.  NOTE: this will likely fail for
    some domains due to SPF/DKIM.
