Offline Web Apps: issues with wittr project from Udacity

https://github.com/jakearchibald/wittr requires Python, gyp and build tools installed. Node and gulp versions in use are way too outdated this triggers project installation errors.

Switching to https://github.com/jakearchibald/wittr-modern partly helps.

Even when builders are installed properly `node-sass` cannot donwload required dependencies.
Tested under windows, course students report similar issues.


**Option 1.**
Using node v11.15.0 helps

**Option 2.** ([source](https://www.notion.so/node-gyp-on-wsl-2ae84a3c412243cb9f78db727a64259d))
on windows powershell/gitbash:
`npm install --global --production windows-build-tools --vs2015`

on wsl:
`sudo apt install python`
`npm install node-gyp make`
`npm install node-sass —save-dev`

The report points to the external jakearchibald/wittr and wittr-modern projects rather than files or tests in this repository. Start by reproducing the installation failure on Windows with the stated Node versions and node-sass/node-gyp commands; done would require an agreed, tested setup or a clearly scoped repository change.
