App.on('error') Not Fired

[blupu]

When network is not available or retrieving data from WS fails, refresh:end event if triggered. At the moment, we don't have the required feedback to know if the call has worked or not.

Apparently App.on('erroe') is never fired.

I added a "result" param to the App.on('refresh:end') callback, that can now be used to handle connexion errors, with something like :

App.on('refresh:end',function(result){
    if ( result.ok ) {
        showMessage("Content updated successfully :)");
    }else{
        showMessage(result.message);
    }
});

I updated the bootstrap and nihao themes to handle this.
Details about this result object are documented in app/core/theme-app.js::themeApp.refresh()

I close the issue unless you want to check why on error is not raised?
