Catch a lot of old URL's and update them. Also remove a couple of old files that aren't used.
Changed the server to use the external util package. Quite a minor change, but does affect a lot of files.
Forgot to make the XMLCache a public class :) And got the XMLPacketWrapper wrong...
Addition of an XMLCache class. This class tries to help cut down on the number of times we parse a single piece of XML. Using this class will ensure that a String of XML is only decoded once within a given JVM. This has been shown to be significantly more efficient than parsing it multiple times in tests. Next step is to integrate this into the rest of the server. I'd also like to investigate tweaking the initial size and loading factor of the HashMaps used within this class.
