Show full year for birthdays in contact details (and elsewhere)
When a contact is:
- over 100,or
- has died, but the contact has been retained,
the birthday field, at least in the contact details pane, is ambiguous, e.g. 1/2/15 could mean 1915 or 2015.
A simple fix would be to display the full year, e.g. 1/2/1915 or 1/2/2015 (or even better, a more friendly format - e.g. 1 January 1915, January 1st 1915 etc. depending on locale).
