Fixed IQM Turret

[Viech]

There is a new iqm model for the turret with fixed animations which needs to be put ingame. Note that the thread above contains further information on the bone setup. Please post a link to a properly versioned pk3 when done. I will then test it and make sure it ends up in the release.

I tried to do this several months ago, but I never got it to work. I will take another look this week.

Fixed the pitch. Yaw still WIP. I can't get the stupid thing to aim at me. By the way, chris needs to make an attack animation (barrel rotating). up on github under the newturret branch if someone else wants to take a stab. It's basically messing with the es->angles2[yaw] - es->angles[yaw] line until it aims at you. GL

I got this. The pk3 is here, test it on the newturret branch.

The only thing I could use to improve the implementation further is a version of the turret that has only the idle animation (the static, neutral pose). For now I added hacks that disable the construction and death animations so that I have full control over the turret inside the gamelogic. (The power related animations I just don't call.)
