Question: How do I tell django-extensions' `shell_plus` what models I want to autoload?

Answer: 
I've made a new patch for the shell\_plus extension that makes it possible to ignore some models. Waiting for <https://github.com/django-extensions/django-extensions/pull/99> to get accepted.
By default `shell_plus` always loads all your models.
Thanks to @xeor you can use the option *SHELL\_PLUS\_DONT\_LOAD* in your settings to skip some of your models.
You can also configure aliases to your models to avoid names collisions.
