my hakyll build/development/deploy/make scripts. replacement `watch` uses inotify to run purifycss which removes unused rules and minifies into one file, which makes the site load much faster, `deploy` uploads to github pages. can also run `hindent` manually for kicks. an html-tidy compiler filter makes sure the html format is good
