    Remove the requirement for SILENCED_SYSTEM_CHECKS, this is actually quite silly but... I don't know any better way to support all Django versions 1.4-1.7

    Avoid calling get_user_model on import time. Restores Django 1.7 compatibility.

    The thing is, on import-time django.setup() was not called which leads
    to errors if you're calling get_user_model on Django 1.7.
fix in 'es' translation
