- changePassword(string oldpw, string newpw) - changes password for the current user only,  old password must be supplied
 - setPassword(string userName, string password) - set the password for the given user - only executable by an admin user
Fix up and clean up of my-sites.get.js so that IMAP favorites are only retrieved if the IMAP server is enabled
