Small Aggregation Documentation Update - Import Line

[Tyler Brownell <tyler@…>]

This change request is for the generating aggregates over a queryset section of the aggregation documentation:
​http://docs.djangoproject.com/en/dev/topics/db/aggregation/#generating-aggregates-over-a-queryset

Please change the following line of code to include the other methods that are used throughout the page:

from django.db.models import Avg

Should be changed to:

from django.db.models import Avg, Max, Min, Count

This way new Django users, like me, know that these methods have to be imported, and imported from django.db.models before they can be used.

(In [9787]) Fixed #10052 -- Added import line for other aggregates used in examples. Thanks to Tyler Brownell <tyler@…> for the suggestion.
