Ability to scale individual axis of mapmodels.

[SniperGoth]

While we can scale mapmodels to any size we want, sometimes it makes me wonder if having the ability to just scale only one or two axis could be useful, specially for helping with modular type models, like the cables, pipes and so on. Otherwise you need to create a duplicate of it, scale it, and then import back inside the game. I feel this would be very useful specially for rocks to give some needed variety when they are placed onto the maps.
