Release 0.8.2

Release 0.8.1.3

Release 0.8.1.1

Add a flag to disable the example executable (and test).

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.
