ofURLFileLoader amend

hi,

ofURLFileLoader is a really nice addition to 007 and is exactly what i needed on my current project.
im using the ofSaveURLAsync() function for saving files from the web to my local machine.
i also register for related events using ofRegisterURLNotification( this );

works great when the file im trying to download exists and i get back a ofHttpResponse object,

  
  
void testApp :: urlResponse ( ofHttpResponse &response )  
{  
    // do stuff  
}  
  

although when the file does not exist or the internet is disconnected it doesn’t return any callback.
this makes it impossible to handle url error events in your app :S

i made a small addition to ofURLFileLoader to allow for error callbacks to be made in here,

}else{  
	lock();  
	ofLog(OF_LOG_VERBOSE,"failed getting request " + requests.front().name);  
	responses.push(response);  
	requests.pop_front();  
	ofAddListener(ofEvents.update,this,&ofURLFileLoader::update);  
	unlock();  
}
