constant_contact 6.x-2.0-rc3

This release adds one new feature (see #3 below) and makes some important fixes and changes, all users are recommended to upgrade.

1.) The module will now keep your username and password to aid upgrades.
2.) Further tweaks to the Installation because of users reporting the same error about openssl.
3.) Added options to let the user select HTML or Text emails.
4.) In the form block, if a user who is already subscribed tries to subscribe they would have previously been re-subscribed, now the module will NOT let let people re-subscribe, they have to login and update their subscription or use the constantcontact.com website, this is to avoid overwriting the lists people are subscribed to if the APi is used elsewhere.
5.) You can now set the position of the email field that appears within the form block.
6.) The module now uses the drupal function module_load_include() instead of require_once.
7.) Fixed a bug with the way class.cc.php handled chunked data.
