A patch from Leon for "HttpClient does not support charset name with quotation mark around" https://issues.apache.org/jira/browse/OFBIZ-5787

In RFC2045 (Section 5.1) there is:
"Content-type: text/plain; charset=us-ascii (Plain text)
Content-type: text/plain; charset="us-ascii"
are completely equivalent".

In current revision, if the 'Content-Type' of http response includes the quotation mark around the charset name, HttpClient throws out unsupported encoding exception.

This patch removes quotation marks from charset name extracted from http response header.
