Upgrading to 0.9.x

Upgrade Checklist

1. Change your process callbacks moving done to last argument (if you are using a 3 arguments version)

   queue.process( 'type', function( job, done, ctx ){});

   is now

   queue.process( 'type', function( job, ctx, done ){});

2. The same has happened to queue.shutdown, so

   queue.shutdown( function( err ){}, 5000 );

   should be changed to

   queue.shutdown( 5000, function( err ){} );

3. Search indexing is now turned off by default, so if you were using this feature in 0.8.x you should now add disableSearch: false to your kue configuration.

4. Remove all queue.promote() calls within your code. Kue will now take care of them himself ;)

5. Built-in web app is upgraded to express 4.0
