Create an Electron project with React that runs Python

[jasozh]

Description

Notable changes:

1. The Electron project skeleton now contains React, along with webpack and typescript.
2. Python files stored inside the python directory are now available both in dev mode and in production. When using the maker-zip maker, Electron can directly call the raw Python files stored inside the resources directory.
