Spin out components for:
* MessageBox: draw a chat message in the chat history panel as well as reused
in the Report Modal.
* WhoListRow: provides a consistent UX for the Who List and Watching tab. On
the Watching tab, the video button is replaced with the boot from video.
Other changes:
* Move VideoFlag into its own separate ES module.
* Emoji available reactions are moved into MessageBox.
* On WhoListRow: usernames are clickable to also open their profile page.
* On WhoListRow: the Watching tab is now sortable and follows the user's
sort selection like the Online tab does.
This commit makes an initial port of the front-end over to a proper Vue
CLI application. It seems to work from surface level testing.
Changes made:
* Rename web/static to public/static to place it into the Vue build path
* Notes: web/static/js/BareRTC.js and web/templates/chat.html are now
deprecated
* Rename web/static/js/sounds.js into src/lib/sounds.js making it a
proper JavaScript module with exports.
* Fill out initial src/App.vue by copying and updating
web/templates/chat.html and web/static/js/BareRTC.js into this module.
