PasswdDlg provides a simple way to display a login/password dialog.
PasswdDlg::create creates the dialog, displays it, and return the value of login
and password in a list, or an empty list if it is destroyed or user press cancel.
When returning, the dialog no longer exists.
Additionnal resources can be set to modify other text:
    *loginName     Label for login LabelEntry
    *passwordName  Label for password LabelEntry
