Add Dan Burton's packages

The addition of my packages successfully passed the `select` and `check` phases (by adding `addRange "temp" "stm-chans" "< 2.1"`, which is an orthagonal issue). I am having other issues building all of Stackage on my machine, but I did test a fresh `cabal install` of all of the packages I added, and can reasonably expect that they will not interfere with anyone else's stuff.
