- cleanup of the virtual function definitions for inventory items. Let's better use 'virtual' and 'override' everywhere to make sure that nothing gets overlooked.

- added call wrappers and script hooks for all relevant virtuals in AInventory.
- made GetSpeedFactor and GetNoTeleportFreeze entirely scripted because they are too trivial - also do them iteratively, just like HandlePickup, because it's just a better way to do this stuff.
