nmbug.js: Add dialog-polyfill dependency for Firefox
It looks like Firefox doesn't support the <dialog> element yet [1,2],
so this commit dynamically loads the polyfill replacement [3]. Since
the polyfill files load asynchronously, I need to use onload to decide
when they've all made it down (setting the async property to false
didn't seem to work).
