Title: Make charsets parsing more relaxed

Certain user agents send invalid Accept-Charset headers, like the
following: "ISO-8859-1;utf-8;q=0.7,*;q=0.7"

The user agent with which this behavior was observed presented itself
with the User-Agent string: "Mozilla/5.0 (Windows; U; Windows NT 5.1;
en-US; rv:1.9) Gecko/2008052906 Firefox/3.0" Although this doesn't
appear to be correct. The request might have been mangled by a
transparent proxy.
