Make Some Files Available Offline

Register file path that need to be available in offline mode in codetmp/sw.js.

self.addEventListener('install', function(event) {
  
  // files listed below will be cached for offline browsing
  let urls = [
    '/',
    '/css/style.css',
    '/assets/ace/ace.js',
    '/assets/ace/theme-codetmp.js',
  ..

Don't forget to increase cacheVersion. Keep in mind that it need to keep increasing, otherwise you will have to tell your users to clear their cache if something went wrong. Currently There's no meaning behind Codetmp version, this might change after v7.3.

let cacheVersion = '7.2782';
