resolves a memory leak in BrickDatabase, adds stability to character save doc. Tested that saving manually via force-save, logout and /crash all saved my position and my removed banana as expected. The doc was always deleted on character destruction and on any updates, so this is just a semantic change (and now we no longer have new'd tinyxml2::documents on the heap)
