The browser:purge-domain-data notification had two different intentions,
- to clear session store information and
- to clear all localStorage and sessionStorage
Firing the notification accomplished both at the same time, which from a
user perspective is of course totally not understandable. This commit
removes purge-domain-data in favor of the two distinct purge-localStorage and
purge-sessionStorage events. This gives callers more granular choice on
what they want to clear.
