Updates to build with stack and upstream changes

I figured this would be harder considering I haven't touched it in far
too long. Didn't take much work at all to get it built and running
again, and all tests (such as they are) pass.

+ stack didn't like the exe and test exe both using Main.hs
+ filled out other-modules in .cabal at stack's suggestion
+ EitherT is now ExceptT
+ pipes-concurrency deprecated `Unbounded` in favor of `unbounded`
+ tasty's wrapper of HSpec is now in IO
+ misc minor hLint changes
