I believe the correct TodoMVC behavior is to hide footer if there are no items present in todo-list.
This commits implements todo items hiding according to filter state in a more (i believe) idiomatic way. Instead of relying on css class to show/hide particular DOM element, when we specify parent component (TodoList) we first filter through app items and call child component (Item) only when it's not hidden according to our display logic (determined by hidden? function). It has a nice side-effect that we don't have to pass [item filter] tuple to Item component as just item us sufficient and also fixes the bug that whenever our filter state was set to 'complete' and we added new todo item, this item was shown in the list even when it should really be hidden in my opinion.
I believe that put! calls are more idiomatic way to put value on core.async channel from callback as we are not interested in establishing state machine created by go macro, it's basically -> 'put the value on channel and i am not interested in rendezvous wit the consumer, there is no need for coordination, thanks' I hope my understanding of core.async is correct though, so please review carefully :)

Hi Luke,
With this pull request, i did some improvements to your todomvc quiescent sample, i divided it into 3 commits, each one implementing one change.
There is still some work to do, for example 'toggle all' functionality is not working at the moment, i will try to fix that too.
