stackage-exec #25

Do the needful.

The natural thing to do is set GHC_PACKAGE_PATH, among other things.

https://downloads.haskell.org/~ghc/7.0.2/docs/html/users_guide/packages.html#ghc-package-path

However, this is incompatible with cabal. In fact, cabal sometimes has problems when run inside of cabal exec. This may be quite tricky to work around.

Implement for Stackage.Environment as in https://github.com/fpco/stackage-common/issues/1.

Note: put in stackage-common

For now, the only workflow supported is the "do things yourself with cabal" workflow. stackage-exec will put the right ghc and cabal on your PATH, and leave it up to you to take it from there.

Let's create new issues for other workflows that we want to support. (e.g. the "run in docker" workflow.)

Detecting the correct versions of things based on a given snapshot is also not done yet. Progress on that is tracked in #23.
