[PEPr] Changes in proposal for Web Services::Services_DynDNS

Bryan Dunlap (http://pear.php.net/user/bdunlap) has edited the proposal for Web Services::Services_DynDNS. Change comment: Added static methods Services_DynDNS::getUserAgent() and Services_DynDNS::setUserAgent() to allow developers to use their own user agent values when developing DynDNS clients (the "User-Agent" HTTP header is required by the DynDNS REST service). If no custom user agent value is set, the package uses SERVICES_DYNDNS_DEFAULT_USER_AGENT as a default value. Added Services_DynDNS_Request_common::addHostname() to allow hostnames to be added to existing Services_DynDNS_Request instances, without having to overwrite the entire parameter using Services_DynDNS_Request_common::setParameter(). Cleaned up docblocks. Please review the proposal: http://pear.php.net/pepr/pepr-proposal-show.php?id=274 -- Sent by PEPr, the automatic proposal system at http://pear.php.net
