Correction to documentation on get(**kwargs) queryset method

[daveyjoe]

Found at: ​http://docs.djangoproject.com/en/dev/ref/models/querysets/#id5

Incorrect text: "get() raises AssertionError if more than one object was found."

Suggested correction: "get() raises a MultipleObjectsReturned exception if more than one object was found. The MultipleObjectsReturned exception is an attribute of the model class."

(In [9257]) Fixed #9420 -- Fixed an exception type in the documentation of Queryset.get().
Based on a suggestion from daveyjoe.

(In [9261]) [1.0.X] Fixed #9420 -- Fixed an exception type in the documentation of
Queryset.get(). Based on a suggestion from daveyjoe.

Backport of r9257 from trunk.

(In [10598]) Fixed #9420 -- Fixed admin templates CSS.

Removed some unconditional, invalid, IE-specific notations that were
protecting IE 5 users. IE 5 is sufficiently old, we don't really need to
do that and helping that small userbase at the expense of everybody else
was a slight priority inversion.

Patch from G2P and reviwed by Wilson Miner (who made the original
changes).

[Collin Anderson]

[10598] actually fixed #9492.
