Aliasing aircraft -> airplane.

Reason: Used to refer to the same thing, airplane more common.

On a seperate note, anthro_airplane or anthro_object or a similar tag may be required to seperate anthro_airplanes, and anthros with airplanes, which currently there is no way to seperate the two.

An airplane is a type of aircraft. Aircraft could refer to a variety of flying objects.

Well, it should be aliased or implicated one way or another regardless.

Implications:

Blimps, zeppelins and airships are all the same sort of thing, so I'm gonna merge them all into airship.
