Hide incompatible functional test generator from nosetests.
Bring moveToZip up to spec with PEP8 and adjust module docstring.

(It still needs unit tests though)
Fix build_manpage and enable installation of unball.tap.

TODO: Still need to redesign build_manpage to operate on a per-command
      rather than per-package basis. (eg. Manpages for "unball" and
      "moveToZip" rather than "Unball")
Begin adding a unit test suite to complement the functional tests.

(So far, only unit tests unball.util.BinYes)
