Nokia's latest Anna firmware broke the Date.toLocaleDateString() method
which no longer returns the localized weekday but a simple "19/08/11"
instead.
The now implemented workaround collects all weekday locales the same way
the month locales are collected: for every weekday, a temporary calendar
entry is created and its resulting startdate fetched back into the app.
This is slow but hopefully will survive further API changes.
