rename executable or lib in cabal to avoid `cabal repl` conflicts

[rvion]

since lib and exe have the same name, with cabal >= 10, we can't use cabal repl. hwide-lib for the lib would allow one to use

cabal repl hwide

and

cabal repl hwide-lib

[JPMoresmau]

I'm not sure I understand. The cabal doc is clear: http://www.haskell.org/cabal/users-guide/developing-packages.html

cabal repl foo
cabal repl exe:foo

So you can disambiguate between the lib and the exe.

you're right, thanks for pointing this out :+1:
