mailchimp 6.x-2.0-beta1

This release includes a MAJOR overhaul of how list data is stored. Previously, there was a variable used for each list and for each setting, and every time we needed to get the available MC lists, we had to query mailchimp. With the new approach all saved lists are stored as an array of objects in the variables table, making them easily accessible and easier to work with.

IMPORTANT NOTE: Settings from previous versions are not carried over and will need to be reapplied on the mailchimp configuration page. Sorry, happy to take suggestions on how I can migrate them.

• the module was incorrectly handling the use case when an email address was updated. It was unsubscribing a user / then resubscribing with the new address, and this may be behind #527964: hook_user is subscribe/unsubscribe users accidentally
• functional separation for required lists. Users subscribed to required lists are added/updated/removed in hook_user during insert, update, or delete operations. Non-required lists are maintained when the profile form is submitted, using form_alter.
• added hook_perm instead of relying on administer site configuration.
• complete refactoring of how the stand alone subscribe form works, including addressing the problem with interest groups, #567384
• checking for tempty token array, #558220: Warning messagem on 6.x-2.x-dev
• added a basic block to display all available lists for a given user
• map MailChimp marge vars to Drupal form fields #433312: Map MailChimp input to Drupal FormAPI (patch attached)
• pass dates in proper format for use in merge vars, #539954: User Edit Page Freezes / Bad Response. Got This: Warning: strtotime() expects parameter 1 to be string, array given
• newest version, MCAPI v1.2.3, of MailChimp PHP library
• moved update/insert functionality out of hook_user and into form_alter with submit handlers. Addresses #527964: hook_user is subscribe/unsubscribe users accidentally.
