title: jQuery validation plugin - numbers only, min & max length - space issue
body: <p>I'm using jQuery Validation (<strong><a href="http://docs.jquery.com/Plugins/Validation/" rel="noreferrer">PLUGIN URL</a></strong>) plugin for most of my form validation: </p>
  
  <p>I have following example (<strong><a href="http://jsfiddle.net/MrTest/7BqxN/19/" rel="noreferrer">LIVE EXAMPLE</a></strong>):</p>
  
  <p><strong>FORM:</strong></p>
  
  <pre><code> &lt;form class="form" id="feedback-form" method="post" action="#"&gt;
  
  
      &lt;label for="phone"&gt;Contact number:&lt;/label&gt;
      &lt;input type="text" value="" id="phone" name="phone" class="required"&gt;
      &lt;br class="clr"&gt;
  
      &lt;div class="form-buttons"&gt;
          &lt;input id="submit" type="submit" value="Submit" class="button" &gt;
      &lt;/div&gt;
      &lt;br class="clr"&gt;
      &lt;br /&gt;&lt;br /&gt;
  
  &lt;/form&gt;
  </code></pre>
  
  <p><strong>jQuery:</strong> </p>
  
  <pre><code>$("#feedback-form").validate({
      rules: {
  
          phone: {
              number: true, // as space is not a number it will return an error
              minlength: 6, // will count space 
              maxlength: 9
          }
  
      }
  
  });
  </code></pre>
  
  <p><strong>I have two issues, both relating to space usage.</strong></p>
  
  <ul>
  <li>min &amp; max length will count space as an character</li>
  <li>if <code>number = true</code> and space is used, it will return error as space is not a number</li>
  </ul>
  
  <p><strong>Is there any workaround this? Have any of you bumped in on the same problem?</strong> Please note I want to keep allowing to type in space (for readability).</p>
