Title: Feature additions in FlxWeapon & FlxSprite

Added some collision helper functions in FlxWeapon, and a setter for the "flipped" property on FlxSprite.

(in order to do this)
```
override private function setFlipped(isFlipped:Int):Int
{
if (isFlipped > 0)
facing = FlxObject.LEFT;
else
facing = FlxObject.RIGHT;
return super.setFlipped(isFlipped);
}
```

Also added number defines for Xbox 360 controller in Joystick.hx and made a crash prevention fix in FlxGroup.
