Merge branch 'master' into travis
rename src/System/Console/Hawk/Config to UserPrelude per #85
display sdist tarball
include Data.HaskellModule in extra source files
comment out the build from sdist stanza
travis build status sticker
comment GHC 7.6.1 and 7.8.1 in travis build
TODO cleanup and references
travis: ghc 7.8 & head environments are allowed failures
try and compile with GHC HEAD
list ALL the files!

Still not sure why we need to do that (can't cabal just grab
everything?), but listing every single haskell file in
Extra-Source-Files does fix an issue with `cabal sdist`. I just wish
there was a way to automate this.
