Support build without Qt session manager
MOC doesn't see the QT_NO_SESSIONMANAGER
define, so leave
the KWMSessionManager
class in place but don't use it.
The slots don't have to be slots anymore with function-pointer
connect syntax, so that no MOC code referencing QSessionManager
is generated either.
