tdf#124245 Polyfills and fixes for IE11

The polyfills can be removed after we drop IE11 support.

Other IE11 fixes:

Change from document.URL to window.location.pathname
because otherwise we get local Windows paths with backward
slashes.

Use clear: left; for google-donation element so it doesn't
float on top of other elements.

Don't use defer to load fuzzysort.js and prism.js.
