bug 1011729 Show list of (easy) tasks on front page

List template is separated into components (filter for tasks + list of tasks) that can be reused on the home page. @bobsilverberg r?
I suggest just having 2 separate templates for the list and for the filters. It would be similar to what you have here, but not including the `task-list-component` at the bottom of the `filtered-list-component`. So in whatever template you happen to be working on you can choose to include just the list and/or just the filters. While the latter seems like it would never happen, it could make layout easier if we end up wanting a different layout for the list + filters on different pages.
