kwalletmanager: use with broken systray

Keywords: opensuse kwallet kde4

If it does not show up in systray as it may happen with KDE 4.3 at the moment, it can be told to open the app window instead of just (not) going to the systray.
killall kwalletmanager
kwalletmanager --show
The kill makes sure any running instances are removed, because it will not start if it is already running in the background.
