Prevent Abuse of Vehicle Extras Menu to Repair Vehicles

[Tyler-9822]

This is to add the configurable functionality to prevent a player from adding or removing extras on a vehicle in order to repair it.

Config options consist of:

• Enabling the core functionality
• The amount of engine damage that can be tolerated before the extras are blocked
• The amount of body damage that can be tolerated before the extras are blocked
  - Enabling a notification to the player when they attempt to change extras, but are not permitted
  - The contents of the notification

Thanks for your PR @Tylerg9822-sudo! I've left a few comments regarding changes. Let me know if I can help any further. Cheers!

Thanks again @Tylerg9822-sudo. I added an extra check that will disable the items in the menu if the vehicle is too damaged prior to opening the menu - it looks like so:

If a player opens the menu and then changes an extra, your check kicks in and prevents the extra change 👍
