This was previously effectively being done by XmlDocument in the multiple passes through the XML.
This change tells XmlReader to ignore whitespace. This also means changing arguments to use XmlReader instead of XmlTextReader (a descendent of XmlReader) directly.
XmlReader.Create() has been the recommend way to create XML readers since .NET 2.0 as per MS SDK and is the only way to specific ignore whitespace settings.
This was working in 0.7.2 but was accidentally removed from 0.7.3.
The --publish option for "save oar" will now save oars stripped of parcel owner information as well as scene object info.
Please use the --publish option if you want to publish oars that may be later loaded by others to the same grid from which they were saved.
The encodings are thread-safe and already used in such a manner in other places.
This isn't done where Byte Order Mark output is suppressed, since Encoding.UTF8 is constructed to output the BOM.
