delete terms of use and privacy policy.

Hello.

Thank you for processing the previous pull request.
This pull request is continuation to the previous my pull request. https://github.com/cloverstudio/Spika-Server/pull/4

I think service provider should be formulated the Privacy Policy and Terms of Use.
Service provider using Spika is, will end up in situations where privacy policy terms and not through the eyes even once resulting in mixed into the product of their own in the context of today.

And, It is also possible that is contrary to copyright this Terms of Use and Privacy Policy.
(Although I'm not a legal expert...)

I think Terms of Use and Privacy Policy remove from the this like reason.
Terms of Use and Privacy Policy should be determined by the contents of the service, service provider should decide the Terms of Service and Privacy Policy.

Please confirm.
Thank you.
