[Haskell-cafe] Adding packages from within ghci session

[Michael Sloan]

I've tested this out but can't get it to work.  Seems like ghci can
only see packages that existed when it was loaded.  Would be a good
thing to add to ghci or intero.

If this was possible, then you could have a ghci macro that ran `stack
build foo`, and, once it completed did `:set -package foo`.
