Support optout status reset in Sailthru Subscribe widget

Enable the option to reset a Sailthru profile's optout status to "valid" when using the Sailthru Subscribe widget. This is supported both via the Widget menu, and via shortcode as described in changelog.md. To protect against spam, the option to secure the widget with reCaptcha is also supported. Instructions to set this up are found in the Sailthru plugin menu.

VIP: Clear cache because of 5.3 changes handling for user_activation_key being read

WordPress 5.3 has updated the way how user_activation_key is being read. It used to be read directly from the database, but in https://core.trac.wordpress.org/changeset/45714 and https://core.trac.wordpress.org/changeset/45716 this has been updated, so it gets read from the WP_User object.

This means that any code updating the user_activation_key for a user has to properly clean the caches, otherwise the key won’t be properly read.
