Removed unnecessary extra linking steps (two of them!). npm install --link should be enough to set up the repositories linking to each other, such that mocha-headless-chrome doesn't download Chromium an O(N) number of times.
Adds flagswappr to settings.ts
Completely gets rid of anything to do with gulp. Projects now compile in-place in src with tests as *.test.(tsx|ts) files and use shenanigans-manager instead of gulp-shenanigans to use package.json scripts as build steps.
Gets rid of completeBuild, completeSetup, createNewRepository, gulp, and gulpSetup commands. Will re-create the non-gulp versions of those next.
