* Added support for dynamically reloading vehicle configurations.

You can now change vehicle behaviour by updating the xml files found in the Config folder. There is an in-game menu option for reloading the data which will apply any changes to all active/future vehicles.

While you can edit, you can also completely break the game if you get it wrong, so edit at your own discretion.

If the config files get corrupt, you can just delete them and they will be regenerated with default values.
