GValue exchange

Hi Tim,

Any chance you'd take a patch to move from exchange_func to
convert_func?

I really want the int->string, etc. conversions, but I think
string->int is a bad idea plus it's a pain to write.

Owen says the rationale for exchange_func is so you can implement
bidirectional conversions with only one function, but I am willing to
type the extra functions and submit them in my patch. ;-)
