Fix platform API documentation build

Fix the edx-documentation link

AC-566 fixing contrast for copyright

Fixed import failures that were preventing the platform API documentation from building. The problem is that the doc building environment doesn't need to install all the Python modules that the platform software does, but when Sphinx tries to import select modules so that it can use autoclass to publish docstrings it tries to import all the modules that are imported by those modules, recursively. I mocked the missing modules.
