Add a debug command to show all possible random point for selected creature. (c2610)

To use it
- You must be GM
- Select a creature and type ".mmap testheight" to view point (using default respawn radius)
- If no selected creature it work around the player char itself.
- You can specify the radius '.mmap testheight 20"
