Prop attached to non-existent prop-point in eyecandy actor's death variant

[s0600204]

In r14743, the following four actors were added:

• art/actors/structures/ptolomies/stall_big
• art/actors/structures/ptolomies/stall_med
• art/actors/structures/ptolomies/stall_small_a
• art/actors/structures/ptolomies/stall_small_b

Unfortunately, each of these actors have, in their death variant, a prop ([...]/ptolemies/farmstead_cart) attached to a prop-point (cart) that doesn't actually exist in the respective meshes.

Thus, when the stalls are used in-game via their respective templates (simulation/templates/other/stall_{*}), should they be destroyed, an error appears:

ERROR: Failed to find matching prop point called "cart" in model "art/meshes/structural/stall_small_a.dae" for actor "stall_small_a"

Fortunately, these templates are not only "eyecandy" but, at present, are only used on one map: scenarios/Napata Reconstruction - a map that is not intended to be playable. Thus running into this error is rare. (Hence the low priority of the ticket.)

Suggested action: Remove the offending prop from the actor files.

I'll have a look.
