Yasu 2.0.3

Systempfleger Yasu 2.0.3 behebt einen unschönen Fehler im Zusammenspiel mit den Schlüsselbund: «So, to completely resolve all keychain problems, I’ve removed every single line of keychain related code from Yasu. For those who were overjoyed that it was added, I’m sorry to have to take the candy away from you. But fear not. I will be working on a proper implementation of keychain storage in a future version.»
