Server event to update mismatched vehicle types list

[Scullyy]

• Adds server event to update the mismatched vehicle types list, this removes the requirement to update the list every time you update your artifacts.
• Moves mismatched types to server due to being required for the event to work, event needs to be server sided to prevent abuse.
• Tested on b3258 with the latest artifacts and txAdmin version as of this PR and working.

Example usage:

TriggerEvent('txAdmin:menu:addMismatchedTypes', {
    caddy3 = 'automobile',
    trailersmall2 = 'trailer',
    scrap = 'automobile',
    tractor3 = 'automobile'
})
