This patch adds support for the de-serialization of primitive arrays. I'm not sure how this will affect primitive wrapper arrays (ie java.lang.Integer) as xstream seems to lump them together. I'd like to say the code was all my work, but all the good parts were adapted from http://jscheme.sourceforge.net/jscheme/src/jsint/Import.java

This should be done in this way to save space if possible:
<int array> 1,2,34,4,5,66,... </int>
