Subject: [PATCH 1/3] Fix conversion of variant list members

Item() returns either a Node* or (with wxUSE_STL=1) a
compatibility_iterator. While the former is silently and erroneously
converted to a Variant using the Variant(void*) overload, the STL
flavor fortunately failed. Dereference the Node*/iterator before
passing it to wxVariant_out_helper(const Variant&).
