Silex v0.46.0

Why upgrade?

Authors who publish packages regularly can remain signed in to the Cloudflare
registry without reauthorizing GitHub every day.

Changes

• silex login now keeps access for 30 days. Publishing or running
  silex login renews it automatically when seven days or less remain,
  for up to 90 days after the initial GitHub authorization.
• silex logout still revokes registry access and removes the local copy
  when the service is reachable.

Impact and migration

The official registry preserves the 24-hour flow for Silex 0.45.0 clients.
Update Silex to use the longer connection. GitHub authorization is required
again after 30 days of inactivity or after 90 days at the latest; no Git
repository or additional permission is required. Public installs remain
anonymous.
