Register Token

Is your feature request related to a problem? Please describe.
A way to make a private Booru that is invitation-based or with a register token without allowing users who are not logged in to see posts

Describe the solution you'd like

1. When registering, enter a token that can be set in the admin settings
2. That guests without an account cannot see posts

It's not super-elegant, but if you want something that can be done today - sites that want to be locked down like this currently run by:

• disabling user signups in the Board Config, then the admin creates accounts for people using the Admin Tools screen
• use the Post Ratings extension to make it so that only images tagged Safe are visible to anonymous users, and then don't mark posts as Safe (the default "unknown" is fine for this purpose)
  (or alternatively, using the web server's built-in HTTP Authentication features)

None of those seem like particularly great options, but being more optimised for this use-case would involve some non-trivial code changes ^^
