Creatures: Flying creatures fall to the ground

[jasongdove]

Description:

Many flying creatures fall to the ground (visually on the client) as they are encountered in the world. This may have to do with movement flags CanFly vs DisableGravity. AshamaneCore does not have this problem.

Expected behaviour:

Flying creatures should stay in the air.

Steps to reproduce the problem:

1. .go xyz -5567.898 -2658.942 88.182 1 5.49
2. Watch Saltspray Gull fall from the sky

You can confirm they are falling on the client (and not the server) by checking position Z with .npc info.
