Django 1.4 Docs broken link to sourcecode live on github

[sethwoodworth]

In the master 1.5 branch of django on github, the modeltests directory was broken up into multiple directories. In the docs on ​complex lookups with q objects there is a link to this test:

https://code.djangoproject.com/browser/django/trunk/tests/modeltests/or_lookups/tests.py

This redirects to the github url:

https://github.com/django/django/tree/master/tests/modeltests/or_lookups/tests.py

The updated link for django version 1.4.5 is:

https://github.com/django/django/blob/1.4.5/tests/modeltests/or_lookups/tests.py

I am not sure how to update this link to keep the code.djangoproject.com url.

The url https://github.com/django/django/blob/stable/1.4.x/tests/modeltests/or_lookups/tests.py uses branches instead of tags to get to the same test url, and wont break when/if 1.4.6 is released.
