Title: Relax cabal requirements for Heroku build

With these changes the Anvil build *almost* passes. I think the Heroku environmental factors are good now and the only problem is updating this project to use new Wai Websockets stuff. Here is the error I get at the end of a mostly successful Anvil build:
