The word "IKOSTargetable" was accidentally deleted from the declaration header of class BodyTarget by my PR KSP-KOS#2460. The SET TARGET command has a check to see if the value being set is an actual target object or just a string name that needs to be looked up. That check was based on seeing if the value could be cast to IKOSTargetable or not. When that was accidentally removed from BodyTarget's header, it broke that check.
I had inserted a check to throw an exception if you try to SET TARGET to an illegal body, one the game won't allow because you currently orbit it. In retrospect, that removes a feature people might have been using, which is that trying to set the target to your current SOI body is a roundabout way to unset the target (the game will refuse the attempt and deselect the target, but the kOS script would be fine with it and wouldn't crash). Changing that into an exception means previously working code could break, so I removed the check again.

Fixes #2495
The term "IKOSTargetable" was accidentally deleted from the declaration header of class
BodyTargetby my PR #2460. This puts it back.It caused the bug because of a place in VesselUtils.SetTarget() where it tries to cast the target value to
IKOSTargetable, and with that term removed from the header,BodyTargetvalues no longer allowed themselves to be thusly casted.
