[patch] admin's base.html template needs to escape {{ title }}

[Gary Wilson <gary.wilson@…>]

The admin's views.main.history view sets the "title" template tag to the string representation of the object, which can contain html.

One of these days someone will just do a global search and replace in the admin, turning }} into |escape }}.

Won't it be good when we have autoescaping templates ;)
