Modifications to javascript_validations(), to support use by loncreatecourse.pm and lonmodifycourse.pm. For loncreatecourse.pm: Javascript function verify_message() now only requires an authentication type, if automated adds set to "Yes" (fix to bug #2468). Same function now requires a Kerberos domain if authtype is set to "krb" when called from loncreatecourse.pm and lonmodifycourse.pm.
Existing javascript code for use of javascript_validations() by other modules (e.g., londropadd.pm -directly) left unchanged, although it should be modified in the future if checking of the autharg field is desired - as written it will always deliver the default, i.e., no alert, regardless of the contents of the autharg field.
