Misleading message for prioritized hauling (reported to Mantis)

[Jimyoda]

This was prompted by a scenario described in this thread: https://ludeon.com/forums/index.php?topic=26413.0

I could Mantis this, but would like someone to validate this as something that should be fixed.

The thread above describes the issue well, but here are the repro steps:
1. Create a small allowed area that the includes some items.
2. Assign a hauler to the allowed area.
3. Create a stockpile outside the allowed area.
4. Choose and right-click an item inside the hauler's allowed area.
5. Observe the message 'Cannot haul item (no empty place configured to store it)'.
6. Check that the stockpile has available space and is in fact configured to store the chosen item.

Naturally the item can't be be hauled by that hauler because they aren't allowed to go where it could be stored. As written, the message is false and misleading to the player. If properly worded, the player would know to check their allowed areas rather than the stockpiles.
A more accurate and helpful message would be...
- No empty place configured within allowed area to store it.
or
- Destination stockpile not within allowed area.
