Yearly stats are being displayed.

Yearly stats are being displayed. the code is similar to the GTK one,
but I advise the reader that it's a bit risky  ( I got an unreproducible
crash but it seems to be fixed now. ). The selection behavior is *weird*
and I have no idea why, but I'm very sleepy - will try to look at
it again tomorrow.
