Releases for MailChimp

* Fixes list now showing for users when allowed for some of their roles but not others. #608962: lists not showing up on user edit form, unless *all* of a user's roles may subscribe
* Fixes users being unable to unsubscribe from account edit forms #608964: unable to unsubscribe from user edit form

Fixes fatal error when enabling block, #606930: Enabling block leads to WSOD

handle case where an admin is editing or creating a user

Fixed a bug where the required lists were not being returned correctly and syncing required lists via cron now works.

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
  

This release incorporates the latest version of the MC API PHP class (v 1.2) and begins to fundamentally restructure the code base, moving away from hook_user to resolve #527964: hook_user is subscribe/unsubscribe users accidentally and other issues.

Seems time for a stable 1.0 release in the 6.x branch. No feature changes, just a code migration and some bug fixes.

First official 2.0 release:
# Update to version 1.1 of the MailChimp API
# Hide list setting form and show error message when there are no lists available
# Reorganizing some of the forms
# splitting out the bio module integration into a separate module
# reset mailchimp account settings
# other misc fixes.

Probably time for a 1.0 release since no new issues have come up.

• MCAPI class updated to the 1.0 version of the API. New API URL and the addition of several methods.
• Fixed issue with too many unsubscribe notices being sent on change, added descriptions to lists, fixed bug where mailchimp was being contacted too often. Cleaned up settings page and provided error message when username/password is wrong.
