JumpjetAccel

This flag is, in fact, NOT parsed. JumpJetAccel is parsed instead.

Typing JumpjetAccel instead will make the JumpJet unit never land in a similar fashion to BalloonHover. As a result, AG-only weapons won't target the unit. Only those with AA=yes.

In theory, mis-casing it can be used as a 'fix' for the problem with BallonHover-ers always willing to occupy the same cell as the target.
