Bulldozer - Caterpillar D7 1.0.0

Well.. not pround how many tricks I had to do in order to work as real bulldozer, but after all it works and feels like one, so I guess this is better.
It's working well 95% of the time.. but at somepoint could brake. Sorry, I did my best.

How to install:
1. Copy all the files (bulldozer.lua, bulldozer.vox and bulldozer.xml) to your LEVEL folder (for example vehicle folder)
2. Copy this code in your LEVEL xml file (for example vehicle.xml)

<instance file="LEVEL/bulldozer.xml" pos="0.0 0.0 0.0" rot="0 0 0"/>

Change position and rotation as you prefer.
3. Play

Thanks to @Rubikow, some of the code I use I have found in his creations.

Future updates:
- Improve the vox model of the tracks
- Sounds
- Add riper
- Working pistons (maybe)
- Better code (if someone can help..)
