Optimization in KDE-PIM
Optimization: Cache instance crypto info. Not necessary to create dbus
interface each time that status change.
Ok for the moment we don't have info when instance config change but
it's not critical as bug.
Will implement soon code to get info when instance config changed.
(necessary to make cache other info as Trash folder etc.) I hope yto
implement it in akademy.
Thanks David for this idea.
