middleware.common.py doesn't parse denied_user_agents

[rickeyski]

I tried to set denied user agents and django raised the error str does not have method .search for user_agent_regex.search. Changing the declaration to re.search(user_agent_regex,request.METAuser agent) fixed the problem. The diff is attached

The docs state that settings.DISALLOWED_USER_AGENTS must be a "list of compiled regular expression objects".

See ​http://docs.djangoproject.com/en/dev/ref/settings/#disallowed-user-agents

You have provided a list of strings instead.

You should write DISALLOWED_USER_AGENTS = (re.compile(....), ...)
