See #790. Time for new designs!

I'd like us to offer a fancier option, something sustainably-produced and ideally certified for labor practices, and of heavier weight and longer lasting quality. Color options may be limited given those constraints, so I'm thinking maybe this is basic black, with the logo of course in two-color white and blue. Also, maybe this one isn't a t-shirt, but a button-down or something. Also note that this should come in both fitted and straight cut.

Red Hat's merch vendor for the Cool Stuff store is http://shop.planetlogoinc.com, so most ideally we find something offered there. But as I understand it we can do something else if need be. (Source elsewhere, ship to logistics for distribution.)

Note that since the logo is involved, this issue needs input from either Máirín Duffy or Madeline Peck.
