* [Virtual Attendants/HTTP Requests/Simulator] Fixed an issue where any provided custom headers on the Virtual Attendant 'Execute HTTP Request' action weren't being sent when using the simulator.  The headers were sent properly otherwise.  This made testing and debugging these behaviors unnecessarily complicated.
* [Virtual Attendants/XML] In Virtual Attendant scripts, the xml_decode($text, $namespaces) function can now accept an array of namespaces as the second argument.  This array should have prefixes as the keys and namespace URLs as the values (e.g. "weather":"http://ws.cdyne.com/WeatherWS/").  This enables XPath to be used on more complex XML responses, like those returned by SOAP.
* [Virtual Attendants/XML] In Virtual Attendant scripts, a new xml_xpath_ns($xml, $prefix, $namespace) function can register a new namespace prefix on an existing $xml object returned by xml_decode().  This enables XPath to be used on more complex XML responses, like those returned by SOAP.
