title: Disable remote validations on client_side_validations gem
body: <p>I'm quite pleased with the gem features. However, the current implementation of server-side validations uses <a href="https://github.com/bcardarella/client_side_validations/issues/226" rel="nofollow">synchronous ajax</a>. Thus, I would like to know if these could be disabled application-wide, so I don't have exclude individual validators everywhere in my views, and also to be able to enable them later in case the implementation changes.</p>
