Halo CE Engineers restored to full function

In halo 1, the engineers were a cut enemy type that was pretty much fully functional-- they have AI, animations, textures/shaders etc. They even had a function that makes the explode on death which was pretty much fully implemented but wasn't working correctly due to some errors in the tags. I gave them effects for their shields, fixed the death explosion, made them able to hold their plasma rifle correctly, and fixed the animations.

this is V 1. 1, where I have fixed the animations so that they do not pop up and down when shot or taking other actions. if you have the old version you should update it. This cleans up the tag directories and makes them less redundant as well.

This was originally uploaded on OpenCarnage, but since that's been under attack for a while, I've decided to post my stuff here as well since people have been asking for it.
