Title trees are now model-based rather than item based. Coming with this is proper item metadata, so the data and UI are finally disconnected, making future development much easier. There are also some minor visual improvements as a result of using a TreeView instead of a TreeWidget.
vWii System Menus now have public versions defined in the database. Public version display code has also been entirely rewritten, as the version displayed in the interface and the version used by the code are no longer the same.
