Update storeConfig.sqf

Lodac, helos prices are waaayyy too low.  I'm proposing some changes here.

Regarding jets and tanks the prices i'm proposing are considering their armor, firepower and gadgets (thermals & ammount of flares). I also modified the prices in the general store (Quadrotors and spawn beacons) and gun store in the "premium" weapons (snipers, LMGs, launchers)

Hope you like..
