Need a means to change password

Now it is only possible to add the account password through the counter generation or by modifying the database file of {path}/grid-app/proxy/db/manager.db

......
h := sha1.New()
io.WriteString(h, password+constPasswordSalt)
passwordHashed := base64.URLEncoding.EncodeToString(h.Sum(nil))
fmt.Println("Hashed PW: " + passwordHashed)
......

Thanks for this app, so useful.
