Add the tommyh-theme recipe.

Put this theme together slowly over several years, finally whipped it up into a nice package format
and figured I'd share.

A simple white-backround theme with bold shades of pastel colors based on a certain designer
named Tommy H.  Although I'm sure he's better at choosing colors you can't blame a guy for
tryin'.

ran `make recipe/tommyh-theme` like the README says (slick setup, btw), went smoothly:
