1. Added back stock physics.

RPA3 RealPanzerchangelog
* Adjusted muzzle energy of tank shells downwards a bit to cater for the below change of the additional damage effect.
* Added HE fragment subammunition effect to AP tank shells.

RPA3 changelog
*Added some extra shell armour hit sounds.
*Added thermobaric wave and spall damage from tank shells as per RHS mod.
*Tank armour hit sounds now audible from inside and outside the tank.
*Refined tank shell submunitions code as per RHS example.
*Adjusted the destroyed tank explosion effect.
*Cleaned out some unused sounds and files.

* Removed the RTC real tank crew script as it is redundant when one uses one of the many AI addons now available that have this in or something similar. The less scripts running the better. This means no more repairs by crew members. The script is available as a seperate addon and mod.

* Made some placeable tank types with different skins for each faction.
* Minor physxs udpate so that max and min omega are calculated with a formula.

* Added more variety to tank explosions and burn effects.

* Better external Leopard 2 driving and idling sound.

* Fixed not all tanks had an anti personnel mine launchable from gunners position using the smoke command.
* Added more detail to SABOT rounds, name, speed and RHA penetration to match.
* Removed crater effect from tank launched anti personnel mine.

* Made tank shells cheaper so the AI is more likely to spend them on targets. So far seen no change in game play at all.
