Bad overflow management in QueryUnsignedAttribute

[mr-potato-head]

When I try to parse 10 000 000 000 (hex : 2 540B E400) with QueryUnsignedAttribute I get 1 410 065 408 (hex : 540B E400).

I was expecting 4 294 967 295 (hex : FFFF FFFF), max value for uint32_t (unsigned int) or better XML_ERROR.

I think this is really dangerous, no ?

Note : I work on a Linux Lubuntu 64 Bits / G++ compiler.

Thanks for all the work done on this beautiful library.
