Vehicles
Added two Glide Unit Vehicles, courtesy of TalonSolid:

• Ford Crown Victoria Police Cruiser
  
• Ford Police Interceptor Utility 2011 Police Cruiser

Pursuit Tech
Revamped the Pursuit Tech tool from scratch:

• Merged both "Racer" and "Unit" tools into one
  
• Remade the utility of the tool more simple - choose the PTs in the Sandbox menu, then left-click your vehicle of choice
  
• Settings only appear for admins; drop-down menus only display settings for the chosen PT, not all at once

Added three new Pursuit Techs:

• Racers - Powerplay: Activating Powerplay triggers the nearest Pursuit Breaker to the driver, forcing it to collapse
  
• Racers - Juggernaut: Juggernaut massively increases the ramming power of your vehicle, making it easier to smash through props and blocking vehicles
  
• Racers & Units - EMP: The Electromagnetic Pulse (EMP) targets and locks onto cars in front before delivering a huge electrostatic pulse that temporarily shuts down their electrical systems
  
• Units - Shock Ram: The Shock Ram creates a sonic shock-wave blast from the front of the vehicle that pushes away and damages any cars caught by it
  
• Units - GPS Dart: The GPS Dart is a vehicle tagging system launched from the front of the vehicle that tags, tracks, and locates a fleeing vehicle

Pursuit

• Force-starting a pursuit now uses the on-screen racing countdown from your main/backup HUD type, or uses a generic fallback one
  
• Added a "Being Fined..." meter when being fined by an AI Unit, and a "Busting" meter when being busted while in a race and pursuit

Racing

• Added an option to randomly assign bodygroups, skins and color for AI vehicles

Chatter Profiles

• Added map-specific address calls for Dispatch; bigcity, construct, dunwood, eastcoast, echocity, flatgrass, goldencity, southbeach, southside, gm_palm_city, gm_tri_polis & gm_wangan
