Minimal controllers and form bindings for future login and signup functionality.
Add tag filtering back, and improve keyboard navigation by also using the tagFilter filter.
Improve quicktext list performance by using the already filtered $scope.filteredQuicktexts in the controller, in the ngRepeat, rather than filtering the list again on the view.
Improve the layout of the quicktexts listing even when we have more details (subject, tags, etc.) for an item.
Improve the UI and form behaviour of the New/Edit quicktext modal.
