title: Centralizing Kendo Validator Custom Rules
body: <p>I plan to have a few custom rules for my kendo validator, that I want to share across all my validators.  In my code on a validator, I have:</p>
  
  <pre><code>rules: {
      bothorblank: function (input) {
          ...
      },
      mutualexclusive: function(input) {
  
      }
  }
  </code></pre>
  
  <p>Since I'm using the open source version, is there an easy way to centralize the rules across all validators?  Is there a static property I set with the rules?  Or is the best way to define a generic method that returns an object, and call that during initialization time?</p>
