Disabling alerts and errors in Django File Uploader
I've noticed that when using showMessage function when initializing plugin it can override default behaviour of the plugin. Problem solved.
I'm using this plugin: https://github.com/zmathew/django-ajax-upload-widget and I'm wondering if there is any way of disabling alerts/notifications when upload fails without changing plugin code? 
I want to use bootstrap notifications instead of this ugly default alert popups, but also I have to use Django Eggs so I can't change the plugin code/files.
In documentation I've seen that I can set plugin behaviour when upload success, but can't see anything about upload fail. Please help.
