Switch the Attica KDE plugin to use KAccounts
This removes the custom KWallet integration in favour of an approach based on the more generic KAccounts framework. It is a work in progress which currently does not allow for creating new accounts (which would be done through saveCredentials), but which does load and use the data from any accounts which already exist.
