Problem and solution with plus sign in email

I found an issue where the email address, if it contains a plus sign (ex: [email protected]), fails to process correctly through the plugin (it fails to recognize that a contact already exists for that email address).

Easy fix for this: In cc_class.php, function subscriberExists, I urlencode $email.

I replace this line:

$call = $this->apiPath.'/contacts?email='.$email;

with

$call = $this->apiPath.'/contacts?email='.urlencode($email);
