Include the test suite in the sourcetarball but do not install it.

I reworked the `MANIFEST.in` to include the whole test suite so it can be used
by distribution packages during build time. It is excluded from the installed
packages automatically.

The inclusion rules for the documentation were also made more verbose to prevent
build artifacts from entering the source tarball (think .pyc files).
