GPerlBoxedWrapperClass for G_TYPE_VALUE_ARRAY

I'm wrapping a GObject-based library with a couple of objects that have array
properties (GParamSpecValueArray).  When I try to set the property on
construction, I get the following error:

internal problem: GType GValueArray (2535808) has not been registered with
GPerl

This seems to be due to the fact that GValueArray is a boxed type, but it has
not been registered with gperl_register_boxed, and there isn't any special code
to handle ValueArray values in gperl_value_from_sv().

I needed a work around to get some minimal functionality for the library
bindings, so I implemented the attached code, which I include in the library
bindings module itself.  This code probably isn't correct (I've only tested it
for integers in the SV-to-GValue direction), and a proper fix should probably
be to implement handling of value arrays at some point higher in the call stack
(say when decoding the property GParamSpecs).
