#69 contacts import - birthday date is wrong

[Paula]

- export contacts with Group,First name,Last name,Birthday date
- delete the contacts in osmo
- import contacts with the generated file

--> the birthday date is wrong, the year and the month are always 1

Till yet I had the birthdays in Star Calc, but I would like to see them in osmo. I would like to import them rather that to type them separately in.

Revision 958 fixes this issue.
