Fix/redo testing

[Steve0Greatness]

Testing is useful in a project like this to help to prevent bugs and regressions caused by changes. At this current moment in time, a good chunk of unit and all integration tests are broken.

Integration tests appear to be broken due to the testing tool (Node TAP) not being properly configured for Webpack (somehow). Whereas most broken unit tests are broken because they're attempting to access browser APIs (mainly window and location, but DOMParser is an issue in one part).

---

location (aliased as window.location) is referenced inside of src/extension-support/extension-manager.js

https://github.com/PenguinMod/PenguinMod-vm/blob/develop/src/extension-support/extension-manager.js#L11-L13

Whereas window is being referenced throughout src/util/sandboxed-javascript-runner.js.

DOMParser is used in src/engine/adapter.js.

Node TAP may not be compatible with these APIs, as it appears to be focused mainly on Node rather than the browser. I don't think the solution is to remove the browser APIs, the solution, instead, is to find an appropriate testing environment that can and will work.

gsa attempted to reinstate them before but it was causing a bunch of build errors that would take a long time to resolve, while other changes were being made and couldnt be put onto the site

This is partly a down the road thing.

fake window using jsdom. i know another mod based of TW that does this.
