The issues that exist with injecting skulpt directly:

1. Python runtime / compiletime errors were not seen on the console
2. Even after upgrading skulpt files, it still did not support python 3.

To solve these issues, we moved to using skulpt npm package.
After the upgarde, the editor supports python 3. And we are able to see runtime / compiletime errors in the Console.

Changes to support this have been done as as part of #901
