Added support for resources.xml from update server... Also added option to download music optionally

I had to edit the XML wrapper a bit, basicilly its constructor can now take a optional
thrid arguement which will tell it to use a resman or open the file directly

Also I added fallback support for the old resouce2.txt so servers don't have to
upgrade if they do not want to
