Update Handler.pm

I had a hard time trying to find why my Excel files of Content-type

application/vnd.openxmlformats-officedocument.spreadsheetml.sheet

(taken from http://blogs.msdn.com/b/vsofficedeveloper/archive/2008/05/08/office-2007-open-xml-mime-types.aspx )

were all corrupt.

Turns out Dancer thinks they are XML (they are zipped XML) because there is "xml" in the content-type.

A quick check on the net made me believe that real xml mime types have the string "xml" as seperate words (maybe with a "+" before it), so I think word boundaries would be good here.

At least they fixed my problem.

Serializer::Mutable: Fix content-type with charset

Previously using a header of
Content-Type: text/xml; charset=utf-8
failed to load the correct serializer, json was used as a fallback.

Serializer::Mutable: Fix reponse content-type

curl -X PUT -k -i \
 -H 'Accept: application/json; charset=UTF-8' \
 -H 'Content-Type: text/xml; charset=UTF-8' \
 -d '<r><elt1>content1</elt1></r>'

failed to find the correct RESPONSE serializer.
Content-Type is the format of the input while Accept is the format for
the response data (output).
