support to set global severity when server sent messages don't have severity field.

[xmlking]

In Grails applications we get error messages as fallows:

wonder if you can make messageSeverityKey optional so that we can globally set Severity if there is no Severity field in server send message.

app.config(["growlProvider", "$httpProvider", function(growlProvider, $httpProvider) {
    growlProvider.messagesKey("errors");
    growlProvider.messageTextKey("message");
    $httpProvider.responseInterceptors.push(growlProvider.serverMessagesInterceptor);
}]);

Grails error message
