Gavril Vertex NA2 3.4 Rework

Thanks for reaching in reports of broken things that were not broken on my end for various reasons (other mods, my Fort version)
I've quickly fixed the texture issues and the police pushbar will now show up. Some unnessesary model files that I accidentally left in were removed as well.

Report any further issues to me please. Otherwise I can't fix them if I don't know about them. Its a huge mod and it isn't all that easy to check each and every part and sometimes I do mistakes too. Thank you!
