* When searching filter the sub-projects collection directly and re-render the list once. Previously a CSS class was added/removed and thus every item was re-rendered. H/t?\194?\160adamsilverstein.
* Only render the first 100 sub-projects of a project. The others can be revealed through a search.
* Add an Ajax handler for the projects data and store the JSON data in browser's local storage.
