Continuing saga of the sizing chart problems for original shirts

Gildan removed the sizing chart entirely from their website again
after yet another redesign. Originally, we deep-linked into files in
their CDN for the charts, but it appears that in 5c72071 that I
introduced cut-and-paste error on the sizing charts. I cannot find
the original links, but finally I simply decided we'd mirror the
files in our CDN, which is where these now link to.

I suspect that I didn't do this to start for worrying about copyright
infringement, but upon second thought, I think it's very reasonably
fair use for us to distribute these images. We bought a lot of
t-shirts from Gildan and just trying to sell through.
