Many variables were missing the `cookiecutter` prefix.
In conf.py:
Added prefix to `project_name` and `description`.
Changed `ChangeMyName` to `cookiecutter.author_name`.
Changed `ChangeToMyName` to `cookiecutter.author_name`.
Don't hard-code year. Use `cookiecutter.year`.
In Makefile and make.bat:
Added prefix to `project_name`.
In LICENSE.rst:
Changed `full_name` to `author_name` and added prefix.
Fix year.
