demos/browsers/networkaccessmanager.cpp fails to compile on Solaris 10/Sun Studio 12 C++

demos/browsers/networkaccessmanager.cpp fails to compile due the line at 189

// check if SSL certificate has been trusted already
QString replyHost = reply->url().host() + ":" + reply->url().port();

reply->url().port(); is a number, so concantenating fails since the destination is Qstring.

Patch included fixes the compile problem.
