Fix crash in observing list whenever catalog configuration was changed.
a.k.a. the "Wishlist-Killer" bug. A very frustrating crash would ensue whenever the catalog configuration options were changed (eg: adding a new custom catalog) and an object was added to the observing wishlist. Before a recent commit, the wishlist would be truncated causing much frustration to the user. The crash occurred because the SkyObjects are de-allocated and re-allocated by SkyMapComposite::reloadDeepSky() every time the catalog configuration objects have changed. Since the ObservingList maintained a QList<SkyObject *> pointers to these SkyObjects, we were often querying dangling pointers, leading to crashes. So addition of the object to the wishlist, although did trigger the bug, was not the root cause. This change fixes the bug (hopefully without inducing any others!). The changes are: 1. Create a clone of the SkyObject in ObservingList This makes add / remove more complicated as they look-up the given object by name, but solves the crash because we have a local copy of the SkyObject even if the CatalogComponent's copy is deleted. 2. Use QSharedPointer<SkyObject> instead of SkyObject * This makes sure that we don't re-create the same object for session plan / wish list. Besides, it is much more cleaner, and takes care of deleting itself etc. Extensive testing is appreciated. And once again, happy 20th Birthday KDE! BUG: 345348 CCMAIL: kstars-devel@kde.org
