Remove code-paths only relevant for IE 11/Edge (non-Chromium based) from the web/ folder

Browse source 
This patch purposely starts small, by removing IE-specific code from various JS/CSS files in the `web/` folder.

There's obviously lots of potential for additional clean-up, especially the removal of no longer necessary polyfills in `src/shared/compatibility.js`, however that will require some care considering that certain polyfills may also be necessary for e.g. Node.js or the Chromium-extension as well.
Generally speaking, once we start removing polyfills it's probably a good idea to consult the compatibility information on https://developer.mozilla.org/ and also https://caniuse.com/ first. (Deciding on the lowest supported Chromium version, for the extension, would also seem like a good idea.)
