kotobukiya rainbow dash (et all) should imply 'humanized'

I don’t know what these things are, but it’s getting pretty annoying that these keep slipping past my blacklist.

Or add the implication because that’s literally what they are? Humanized ponies? These tags don’t imply the “Kotobykiya” tag either and people aren’t adding those. S’cuse me for trying to make the tags on images proper.

The tag would also go on EQG and pony fanart versions of the sculpts, so probably not a good idea.
 
In any case, I mass-tagged humanized on the appropriate images.
