[runtimes] Apply skeleton.scaleX/scaleY to wind and gravity

[davidetan]

PhysicsConstraint are not currently considering skeleton.scaleX and skeleton.scaleY wind and gravity during update.

This line of code should be modified.

From:

float m = massInverse * t, e = strength, w = wind * f, g = gravity * f;

or on variable-yDown platforms

float m = massInverse * t, e = strength, w = wind * f, g = (Bone.yDown ? -gravity : gravity) * f;

To:

float m = massInverse * t, e = strength, w = wind * f * skeleton.scaleX, g = gravity * f * skeleton.scaleY;

We don't need to do that here.

To test the effectivness of the fix, just run cloud-pot example with rain animation and change skeleton.scaleX and skeleton.scaleY to 0.5.

Note that (Bone.yDown ? -gravity : gravity) needs to be replaced with just gravity because skeleton.scaleY already includes the yDown -1 sign.
