- Fixed consistency error with the default Tank model (illegal parameter with the materials)

- Adjusted materials
- I'm unable to fix the consistency error with the default tank model. The files are included with the package, but they're in a different folder, so if anyone wants to have a run with it, you need to put the files to the correct place and then repackage them. However, you need to run sv_consistency 0 command to get the game working.

- Adjusted materials
- Added eyeglow effect
