Punctured tires in N Spray

This has now been fixed.

Personal vehicles save two pieces of data to the database - the vehicle's current tires' health, and the max health (for bullet resistant tires). When I first added the bullet-resistant tires, the max health was specified as '0', which the script was to see as 'default'. Due to changes in the backend system that handles vehicle tire health, it now expects '5' and not '0', so when it loads old personal vehicles, it sets their max tire health to 0 and not 5. Consequencely, when you repair said vehicle's tires, they get 'repaired' to the 'max health', which is incorrectly set to 0.

I ran a query on the database to set all personal vehicle max tire healths to 5 if they were 0. No script update required. Sorry for any inconvinience caused.
