@short reset all internal structures
@descr If someone recycles this instance, he can switch from one
using mode to another one. But then we have to reset all currently
used information. Otherwise we mix it and they can make trouble.
But note: that does not set defaults for internal used members, which
does not relate to any job property! e.g. the reference to the global
uno service manager. Such information is used for internal processes only
and are necessary for our work.
