Thanks to @fluesvamp for bringing these to my attention.

GHC's build currently can't handle packages with both a library and
a binary.  Help out by allowing a build to disable the executable,
which is only needed for the test.  (So disable the test as well.)

Also bump the version to 0.8.0.1.

There are also a couple of other monads that could plausibly have this
instance, but since none of them seem to be exported I left them alone.

Helps fix `stack upload`.

Also bump to 0.7.4.2.

Fixes #54.

This lets Hackage pick it up automatically.

Updating the minor version number since we've added 'catches'
to System.Console.Haskeline.MonadException.
