WebKit delegates this responsibility to the application. 
-[WebPolicyDelegate 
webView:decidePolicyForMIMEType:request:frame:decisionListener:] is the 
call the application can use to invoke a helper application. See 
<http://developer.apple.com/documentation/Cocoa/Reference/WebKit/Protocols/WebPolicyDelegate_Protocol/Reference/Reference.html#//apple_ref/occ/instm/NSObject/webView:decidePolicyForMIMEType:request:frame:decisionListener:>
