Docker crosses filesystems.

Zip output corrupts the output for returning the output directory.

To get pip's platform.

We can't easily predict what the output directory will be for a Github
release archive.  Get fetch_unpack to tell us.  Add some tests that
won't fail, but at least show us the output.

Previous version was using a sub-shell to execute, and therefore not
catching errors during execution of the functions that had errors, but
did not return non-0 exit codes.

Add tests.

Thanks to Andrew Murray for pointing out this bug.

It appears that is_function actually
calls the function (debugged). Why
that happens is a mystery to me, but
this should ensure that the spinner
runs as it is supposed to rather than
waiting until pre_build is complete.

Fix "cd" overridden by RVM.
Don't try to uninstall virtualenv if pip is not installed.

Add tests for fill of pypy versions, give full versions for latest.

This changes how the the Python implementation is selected.  It's now
primarily based on enviroment variables.

Uses the PYPY_VERSION enviroment variable to determine the version of PyPy to
install.  An example has been added to the matrix in the readme.
