[FIXED] Edit day in timetable and more

-Now it is allowed to edit the day when you add a session,

a contribution or a break. Also when you edit them.

-When changing the day, the hour will be automatically changed

to the first possible one according to the day selected.

-If you create or edit a break or a contribution inside a session but for

a different day, it will be created outside the session.

-If you move a session from one day to another in the top-level timetable

it will move as well all the breaks or contributions that the session has inside.

-fixes #46
