Carts should now be able to idle on slopes at world load without derailing.
Carts now more robust with attaching their unity script at world load if ManagerSync hasn't loaded yet.

Carts now make additional attempts to find valid depots to return to rather than derailing immediately if the depot's hoppers are full.

Network sync now includes displaying of floating combat text on choosing a destination

Network sync is roughly 75% there I'd say. Carts are now more or less server authoritative. State, destination, inventory are all now exclusively handled by the server. Station (un)loading and pathing are now sync'd over the network. Haven't figured out how to get the floating combat text sync'd yet. Will dig into that more with the next patch.
