title: Prevent ASP.NET MVC Bundles Loading more than once
body: <p>is there an inbuilt method of tracking if a bundle has already been loaded? I have several edit views which forexample require jquery and jquery.Validate etc libraries. Which i don't need to reference on the main layout page. 
  Since a page could consist of several different conditional libraries ... ideally i would like @scripts.Render to know if i have already referenced a library and prevent its reloading.</p>
  
  <p>Cheers
  Tim</p>
