Subject: [PATCH] Make 'token' HTTP header name comparison case-insensitive

HTTP header names are case-insensitive. With the new QHttpHeaders class
in use at the client-side (the colorpaletteclient app in qtdoc), the
request will contain a lower-cased 'token' header => change the
server-side to ignore casing

Task-number: QTBUG-114649
