The class NetworkAccessManager sub-classes QNetworkAccessManager adding a message box to ask the user if SSL errors may be ignored. Ignored errors are ignored in future server replies so that the user is not asked about he same peer certificate chain repeatedly. The cache is currently per process only and not persistent. git-svn-id: svn+ssh://svn.code.sf.net/p/wsjt/wsjt/branches/wsjtx@7361 ab8295b8-cf94-4d9e-aec4-7959e3be5d79
