Update email validation

[VBGAMER45]

Subs-OneAllSocialLogin.php
From
// The email address is invalid.
elseif (!preg_match('^[0-9A-Za-z=+-/][0-9A-Za-z='+-/.]@[\w-]+(.[\w-]+)(.[\w]{2,6})$', $oasl_user_email))

To
// The email address is invalid.
elseif (filter_var($oasl_user_email, FILTER_VALIDATE_EMAIL) === false)

This will handle all TLD's better
