make SwNavigationMgr use the shared_ptr

- also make it listen to at least one of the SwUnoCrsr it keeps on the
heap for document disposing.
- as the SwNavigationMgr lives longer than the document this was actually a
double free before: first from SwUnoCrsrTbl dtor an then from the
shared_ptr in SwNavigationMgr
