mock.app.App now tells mock.app.Event that the xml file strings are XMLFileType.Contents.

Made network.MessageEncoders.RaceVisionByteEncoder methods static (they were effectively static already).

shared.dataInput.XMLReader#readXMLFileToString(..) now throws an XMLReaderException if the file cannot be found.

visualiser.Controllers.StartController assumed XML messages were resource paths instead of file contents - fixed.

Testing:
networking tests now work again.
