Gavril Vertex NA2 3.4 Rework

Yes, I've learned my lesson. I'll let others test if it works fine first before throwing it into the public. Anyways, pressing space (aka the "shoot" control for the cannon) would break the car previously. That has been resolved and the control no longer overwrites the keyboard handbrake control. I've also changed the hydraulics controls and added a file path for your own music.
Above that, exhaust muffling was added and the stock i4 and 4.5l V8 now have less momentum when revving.
This version should finally be free of big issues. Only took me 5 updates lmao.
If you experience any more issues, please report them. Sorry that it took that many updates to finally get most of the issues out of the world. At least neither me or my testers can't find anything broken

Full Changelog:

• Fixed fatal lua error when pressing space bar when the cannon isnt applies
• Fixed ridicilous engine momentum when revving i4 and v8
• Added exhaust muffling to all engines
  
• Made Bosozoku exhaust available for V6
• Changed Semi Turbo model for inline 4 engine, thanks to a nice person on Discord
• Rearranged controls for hydraulics and cannon
  
• Removed Herobrine How long should I keep referencing Minecraft?

So, have fun with the most bug free version of the Vertex in existence. For now
