Adding a todo to add a User_::readSafe()

- The JWT token only contains the issuer, and your user id now.
- Now only a page refresh is necessary to pick up your settings on all
  clients, including theme, language, etc.
- GetSiteResponse now gives you your user and settings if logged in.
- Fixes #773
