Affiliate Royale Integration

## Added integration with the Affiliate Royale WP plugin.
The Are You A Human PlayThru(tm) will be shown on signup pages if enabled under Plugins->Are You A Human->Settings->Enable PlayThru on->Registration Form.

## Updates to Affiliate Royale code are needed to support PlayThru on Reset Password page.
At the time this code is being written, Affiliate Royale does not fire any actions/filters on:
1. the Reset Password page (`affiliate-royale/classes/views/forgot_password.php`):
**Suggest adding the following code at the bottom of the above-mentioned form:**
`<?php do_action('wafp-user-forgot-password-fields'); ?>`
2. inside the Reset Password validation method (`affiliate-royale/classes/models/WafpUser.php`) 
**Suggest adding the following code at the top of the method: `WafpUser::validate_forgot_password()`**
`$errors = apply_filters('wafp-validate-forgot-password', $errors);`
