title: Backbone.js catch events by RegEx?
body: <p>I was looking around but could not find anything whether it's possible to add event listener by RegEx rule?</p>
  
  <p>I.e.:</p>
  
  <pre><code>EventBus.trigger('catalog:filter');
  EventBus.trigger('catalog:removed');
  </code></pre>
  
  <p>And I want to catch them in two different ways:
  1) By binding directly on event i.e.:</p>
  
  <pre><code>EventBus.on('catalog:filter', callback);
  </code></pre>
  
  <p>2) By binding for RegEx test and catching all events of that type i.e.:</p>
  
  <pre><code>EventBus.on(/catalog/, callback);
  </code></pre>
  
  <p>The second one should catch and handle both events 'catalog:filter' and 'catalog:removed'. This is in a way the same as model "change" and "change:[attribute]" way to bind events. It doesn't nesseceraly have to be RegEx object to work.</p>
  
  <p>Thank you</p>
