Another attempt at parsing MOAP <Media> elements in OAR files.

Browse Source 
Seems there are multiple interpretations of the format of the content of the
<Media> element in OAR files. OpenSimulator (for reasons lost in the mist of time)
escapes the XML in the element and then reparses it was a separate XmlReader.
Other simulators fill the <Media> element with regular XML.

This patch parses the <Media> escaped XML content as it always has and, if
the parsing fails, falls back to trying to parse the pure XML.
