Courier's Coalition Assignments - Easing bivouac supply runs

[pancakesandsx]

Allow us (via the same courier's coalition upgrade that adds delivery npcs) to accept a bivouac supply quest from a frontier station.

Alternatively, if the quest cannot be accepted from an alternate location, after accepting the imprimatur quest from the coalition, make players pick up the supplies key item from the frontier station in the appropriate zone, rather than accepting the ki from the coalition itself. This would allow players to teleport to the zone first, and then make their delivery.

This would ease the travel time to reach far off bivouacs on foot. Making the delivery within the zone is difficult enough with the hazards of reives etc, making the trip across multiple zones is simply unreasonable, and will only get worse as more zones are added farther and farther from Adoulin.
