This achieves the result by counting up the number of highlights across all rooms and setting that as the badge above the icon. If there are no highlights, nothing is displayed. The red highlight on the bell is done by abusing how the Tinter works: because it has access to the properties of the SVG that we'd need to override it, we give it a collection of colors it should use instead of the theme/tint it is trying to apply. This results in the Tinter using our warning color instead of whatever it was going to apply.
The RightPanel now listens for events to update the count too, otherwise when the user receives a ping they'd have to switch rooms to see the change.
If you happen to get logged out, it might not be very clear what has happened
visually. This adds a visible warning to the top of the home page to suggest
logging in.

Display an error on the splash screen with the spinner if the sync
request is not working, rather than just sitting there with a spinner
as if nothing is wrong.
