Title: No way to stack progress activity views

When sending off multiple async requests it's nice to be able to stack
activity indicators instead of keeping track of when all the async
requests have finished then dismissing the activity indicator.

I also updated the example.

I basically copied the way RestKit handles the networkActivityView spinner.
