[Improvement] M class subordinate gate crossing

[Xkuka]

Currently M class ships assigned to a commander following in formation use all their boost energy to get away from the gate after crossing.
This behavior is not very smart nor useful. Especially on combat missions these corvettes separate themselves from their fleet and expose their bare hull. It takes a while to reload the shields, so these corvettes are not even combat ready for a little while.
If this is intended to prevent collision, please, use the travel drive. There is no reason whatsoever to use the boost to travel like 20km into the sector and then be vulnerable to all kinds of threats, only to regroup then again close to the gate.
If the boost is necessary in case that the travel charge time for certain ships is to slow, it still is preferable to only use a fraction of shield energy to make a hasty move away from the gate.

Thanks
