Set airborne condition for jumper sequences

[mfzl]

There's already a PR #786 for fly sequence, but that doesn't completely fix the problem as I get the following after the fix.

Another option is to define these sequences for spy, but then it looks really weird and it's a dead give-away.

Don't commit lua51.so

@Mailaender thanks for catching this. It was accidental

[Mailaender]

Can you squash your commits?

This fixes the crash, but spy just continues to use its own sprites if you try to disguise it as a Rocketeer, which as abcdefg30 pointed out in #786, you could do in the original game.

This seems to be how bodies for rocketeer set up in Romanov's Vengeance and does the job of giving the spies Rocketeer's ground walk anim:

	WithInfantryBody:
		RequiresCondition: !airborne
	WithInfantryBody@Air:
		StandSequences: fly
		MoveSequence: fly
		DefaultAttackSequence: shoot-air
		IdleSequences: idle-air
		RequiresCondition: airborne
