Rewrite intel probe to be fully airborne

[Exotic-Retard]

This is in preparation for its new model the probe should target an area above the target location and when its there it should stop and hang in mid air instead of hitting the ground.

the idea is for the model to then deploy into a hovering position above with a little unpack animation with radar and stuff like that.
nothing to stop the functionality itself working though. should also fix bugs with slight targetting inaccuracy as well.
