CVS commit by lucijan: 

* fixed a bug which only allowed input of formulas instead of normal numbers
* database manipulation follows referencial integrity!
e.i.

best view with fixed fonts ;)

+-----------+    +-----------+
| timetable |    | subjects  |
+-----------+    +-----------+
| * ID      | -->| * ID      |
| weekday   | |  | name      |
| lesson    | |  +-----------+
| subject   |-
+-----------+

and a query which selects timetable.ID, subjects.name

now, a we change subject.name timetable.subject is automatically set to the right ID
