Thanks Ihor.

I don't get random failures anymore.  And thanks for fixing the tests
that were incorrect.

Thanks Pareto for mentioning the possibiliy to customize GHCi prompts.

About :results output vs :results value, I decided to use the "it"
variable, i.e. to ask GHCi what was the last value (see [1]).

About sessions, I decided to rename the buffer as you suggested. That's
a partial workaround that should work well enough, until haskell-mode
provides a way to choose the buffer name.

I've updated the tests and the expected results.

Note that I've changed the tests about errors; I'm now expecting
ob-haskell to raise errors. I'm not sure what we should expect to be
consistent with other org babel backends.

I also did some modifications in my initial patch in-place.
