Saving and loading angular velocity

[JustinDMS]

To replicate:

1. Save position
2. Get/enable IS
3. Load position (via pause menu or dpad shortcut)

Doing this will bring the morph ball shell back if you currently have an IS state. It can also be observed being reset to zero through the on screen display when loading position from the pause menu.

Done on latest release v2.6.1

Upon further inspection, the angular velocity is not being reset. It's being set to whatever it was at the time of saving position.

One possible fix for this would be to not save/load angular velocity at all. This would allow for more flexibility when testing IS-related things.
