* In place of the Help and Settings buttons, add a hamburger menu
dropdown and place the links under there.
* Also in the dropdown is Close All Cameras and Mute All Cameras (if you
have any cams open; the links are hidden if not)
* Also in the dropdown add a Logout button that just links to a new
/logout route in order to unload the page and align with some users'
expectations (not knowing closing out of the chat page was enough to
log out of the room before)
* Bring back "(offline)" indicators when a user is no longer in the
room.
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.
