-New sprites APC sprites by TankNut!

-New wraith sprites by TankNut!
-Decreased flare duration, again(!)
-Made a based interact proc and changed the updateDialog to call that instead of attack_hand. This caused issues with the APC and getting the power cell out of it. I then changed all machines that had their own defined proc (that was everywhere)
