Todo app

[Anton Danilchenko]

I have commit fixed todo application. Now you can add new tasks and show all tasks.

We need:

 * edit and delete tasks

 * if user click on "Create new task" we need not open new page. But we need show new record before all taks and send form with AJAX request

 * also we need edit tasks inline with AJAX request

 * completed tasks should be shown after actual active tasks in separate section "Completed tasks"

 * user should set task completed inline by set checkbox

We need your help to do this tasks. You can learn more about GAE framework if try do this simple tasks.
