create alias cracked_lens -> cracked_glass
Unless there are glass-less lenses I think this is better because it can be used for things like windows and cups made of glass as well, I had even forgotten this tag existed and just simple tagged it crack.
Well a decent chunk of gla... spectacles' lenses are probably made out of plastic.
I wouldn't tag those broken_glass because I can't be sure, though I wouldn't really mind if those get auto-implicated/aliased.
There are also metal lenses, but those aren't likely to come up. Crystal ones... probably more likely. But don't think we have significant examples anyhow.
That said, broken glass can also be used for the latter purpose, as blindVirgil mentions.
