Black Undershirt alias

The bulk update request #11558 has been rejected.

create alias black_undershirt -> black_shirt

It's dumb to have a separate tag for this when the normal tag works just as fine.

It could be used for finding something like post #5553090 if you remember a girl had a coloured top with a differently coloured undershirt.

Well we don't have any other color_undershirt tags so if we want them separate then other colors will have to be populated as well. I've just been tagging undershirts as color_shirt + undershirt.
