fix for AttributeList_getValue

Hi,

I still had the "No matching function for overloaded 'AttributeList_getValue'"
problem with XML::Xerces v. 2.5.0-0 on my Solaris machine, so I did a
little digging on my own.

The arithmetic '+' in the for loop is turning $i into a
double-precision value instead of an integer. I don't know how you
would get SWIG to automatically do this when it's generating code, but
if you change SvIOK to SvNIOK in the XSUB, it works beautifully.  (see
patch below)

In a pinch, you could change the to_hash() method to use "$i = int($i
+ 1)" instead of "$i++", but that would only mask the symptom.

Hope this helps,
Philip
