Title: \ are allowed in valid key strings

Example of key with backslash can be found here : https://github.com/FriendsOfSymfony/FOSUserBundle/blob/master/Resources/doc/index.md#step-4-configure-your-applications-securityyml

Also fixed the indentation (was mainly 4 spaces but included some tabs, now only 4 spaces).
