fix for cf7

git-svn-id: https://plugins.svn.wordpress.org/are-you-a-human/trunk@969816 b8457f37-d9ea-0310-8a92-e5e31aec5664
WP-Members integration. Two fixes needed: editing one's own user profile does not require a PlayThru but the user receives a "We couldn't verify you're human" error. Also, need no-cache headers added to login pages as well as a "click here to try again" link on the failed PlayThru screen to give users something more convenient than the back button.
Removed spurious indent
Merge remote-tracking branch 'upstream/master'
Merge branch 'master' into feature/wp-members
Added a proper check to make sure we only expect PlayThru on a registration or password reset.
Merge branch 'feature/wp-members' into develop
