[glibmm] Gio::Variant: Add some get() method overloads.

[Murray Cumming <murrayc src gnome org>]

commit 3f08a14a7228adf5540adbc4e84074979a27d47a
Author: Murray Cumming <murrayc murrayc com>
Date:   Wed Mar 16 12:07:01 2011 +0100

    Gio::Variant: Add some get() method overloads.
    
    * glib/src/variant.[hg|ccg]: Variant<VariantBase>: Add a get(VariantBase&)
    along with the existing VariantBase get().
    VariantContainerBase: Added a VariantBase get() to match the existing
    get(VariantBase&). Both seem useful, particularly now that we can
    cast_dynamic them.
    
    VariantContainerBase::get() should maybe be renamed to get_child() too.
