Changes

* Queued deliveries can be reassigned via the manage-delveries menu if a wagoner is dismissed. Deliveries reassigned this way will not be refunded and will be carried out normally.

* Wagoners may have several deliveries queued - each simultaneously-active delivery requires its own crate rack. The wagoner will work through the deliveries in order, returning to their home camp after each one.

* A maximum of one wagoner camp may be placed per waystone
