wrong usage of anonymizeIp

Hi,

google-analycator use a wrong implementation of anonymizeIp, which is necessary for german users.

Wrong:

ga('create', '<?php echo $uid; ?>', 'auto');
<?php if(get_option(key_ga_enhanced_link_attr) == ga_enabled): ?>
        ga('require', 'linkid', 'linkid.js');
<?php endif; ?>
        ga('send', 'pageview');
<?php if ($need_to_annon == '1' ): ?>
        ga('set', 'anonymizeIp', true);
<?php endif; ?>

Correct:

ga('create', '<?php echo $uid; ?>', 'auto');
<?php if(get_option(key_ga_enhanced_link_attr) == ga_enabled): ?>
        ga('require', 'linkid', 'linkid.js');
<?php endif; ?>
<?php if ($need_to_annon == '1' ): ?>
        ga('set', 'anonymizeIp', true);
<?php endif; ?>
        ga('send', 'pageview');

Background: Google requests that IP anonymization/masking takes place as soon as data is received by the Google Analytics Collection Network, before any storage or processing takes place.
