UL values in XML cause NumberFormatException when > 2^31

[ronshapiro7]

Issue #277 changed it to output the UL as an unsigned integer.

However, now when the value is greater than 2^31, it causes a NumberFormatException when reading the XML.

The following 1 line patch fixes the StringUtils to handle the unsigned integer on read:
