Add command to Jester menu to re-calibrate INS on ground

[zippoa]

When flying for long time on one vessel with multiple landings, INS starts to drift. This can be seen by doubling radar contacts (Two contacts near each other instead of one) My human RIO was able to re-calibrate to remove this drift. I think Jester should be able to do it too

thank you, this is a great suggestion. We will look into it, if we can do that.
