Removed spurious "error" in ofTrueTypeFont::initWindows
Added ofxUDPManager::HasSocket to see if socket has been created
Changed GetRemoteAddr to be safer by using a string& for the string rather than an unspecified-length char*. Also added a parameter to retrieve the port (previously inaccessible)
Added GetListenAddr to match GetRemoteAddr but for our "server" socket
Removed m_iListenPort (unused)
ofxUDPManager::Receive() now returns 0 instead of -1/SOCKET_ERROR if WOULDBLOCK is returned
