app: bundle jekyll docs into app, add 'yarn run docs' to build
ui: add back/forward arrows for app only, adjust responsiveness for app, add IS_APP flag injected via preload
ui: add animated logo, friendly message on empty replay frame
app: improve serve logic:
- serve static files from static root
- serve replay from http localhost instead to avoid proxying https for remote requests
- serve local lookup from http prefix also
- catch any fallthrough from replay as 404
- add timestamp to response channels to ensure uniqness
- use webpack to build electron-main and electron-preload
- intercept 'https' protocol to run on 'https://replayweb.page' in app
- serve local files from 'https://files.replayweb.page'
- support flash in with service worker replay: catch any fallthrough urls and load via intercept with render process callback
- add icons for electron build
