Tag alias: crane_game -> ufo_catcher

crane_game -> ufo_catcher

Is there any particular reason for having two separate tags? Looks pretty much the same to me.

I think aliasing ufo_catcher -> crane_game or both to claw_crane would be better.

I think we can use (what I assume is) the more common English phrase since this is not (again, me assuming) something that originated in Japan or anything.

Unless ufo_catcher is a very common term for it in English, I dunno. Aliasing to crane_game for now.
