User Story and Sprint Association

Sprints now represent association of user stories. This is a change from a
selection of tasks.
Add Users to Task Assignment

When creating or editing user stories it is now possible to add a user to the
task. The only way at this point to get users into the application is with a
manual insert with sqlite. But if there are users available the drop down will
show all available users and when you select one it is attributed to the task.
