We use `export default` begrudgingly here. Ideally we'd use just `export`, though this entire SDK expects things to be exported as a default. Instead of breaking everything, we'll sacrifice our export pattern for a smaller diff - a later commit can always do the default export -> regular export conversion.
Adds UI control for 3 hidden notification rules:
* Messages containing @room
* Encrypted one-to-one messages
* Encrypted group messages
This should help to clarify some mysterious notification behavior, as it wasn't
obvious that these rules existed.
Fixesvector-im/riot-web#7833.
